TOLC-I Preparation: Complete Guide to the Test

The TOLC-I is the entrance test for Engineering administered by CISIA: 50 questions on mathematics, logic, sciences and verbal comprehension in 110 minutes. The national average is 20-22 out of 50 — to be competitive you should aim for 25-30. Preparation requires method, realistic simulations and targeted work on weak areas.

If you are reading this guide, you have probably already realised that the TOLC-I is not a formality. It is the test that decides whether you get into Engineering — and where. It is not impossible, but taking it lightly is the fastest way to end up with an OFA in mathematics or, worse, out of the ranking for the programme you wanted.

This guide brings together everything we have learned preparing students for the TOLC-I in recent years: from the test structure to strategies for each section, from the most common mistakes to a week-by-week study plan. This is not a summary of CISIA regulations — you can find that on their website. Here we talk about how to actually prepare.

What is the TOLC-I and why it matters

The TOLC-I (Test Online CISIA for Engineering) is the standard entrance exam for Engineering at most Italian universities. Some use it as a selective test with rankings, others as an orientation test that assigns OFAs below a certain threshold. You can take it from your fourth year of high school and retake it once per month — the best score counts.

A couple of important things to clarify right away:

There is no universal minimum score. Each university sets its own thresholds. Politecnico di Milano converts the TOLC-I score to a 100-point scale according to its own tables — details are on the Politecnico di Milano admission page. The University of Parma requires at least 16/50 total and 4/20 in mathematics. Bologna has yet different criteria. The advice is simple but essential: read the call for applications of the university you want to attend. Don't trust what your classmate read for a different university.

You can retake it once a month. If the first attempt goes poorly, you can try again the following month. You don't have to wait exactly 30 days — just a different calendar month. This is a huge advantage compared to other tests, but it is not an excuse to show up unprepared on the first attempt. Each attempt costs approximately €30 (for a complete cost overview, see our pricing page), and more importantly, each failed attempt erodes confidence.

You can take it from the fourth year of high school. A strategic option: take the TOLC-I in your fourth year, understand where you stand, and have an entire year to improve weak areas. Some universities, such as Politecnico di Milano, offer early admission for those who achieve high scores already in the fourth year.

The test structure: numbers you need to know by heart

The TOLC-I has 50 multiple-choice questions divided into 4 sections with dedicated time: mathematics (20 questions, 50 min), logic (10, 20 min), sciences (10, 20 min) and reading comprehension (10, 20 min). Time per section is not cumulative: when it expires, you move to the next section without being able to go back.

You can check the official TOLC-I structure on the CISIA website for the full syllabus details.

Total duration: 110 minutes for the main part + 15 for English = 125 minutes overall.

The detail many underestimate: time is per section, not cumulative. When the 50 minutes for mathematics expire, you move to logic — you cannot go back. You cannot "save" time on verbal comprehension to use in mathematics. This radically changes the strategy compared to a single-timed test.

How scoring works (and the penalty)

TOLC-I scoring works like this: +1 for correct, 0 for unanswered, -0.25 for wrong. The theoretical maximum is 50, the national average is 20-22. The penalty makes random guessing neutral, but answering is worth it if you can eliminate at least one option.

The system is simple but has important strategic implications:

• Correct answer: +1 point
• No answer: 0 points
• Wrong answer: -0.25 points

The maximum theoretical score is 50. The -0.25 penalty means that guessing randomly among 5 options has a zero expected value (you gain 1 in 20% of cases, lose 0.25 in 80% — break even). But "it works out randomly" and "it works in practice" are two different things. If you can eliminate even one option, answering becomes advantageous. If you have no idea where the answer is, leave it blank.

The national average for the TOLC-I is around 20-22 points out of 50. For most universities, a score between 25 and 30 puts you in a solid position — you avoid OFAs and have margin in the rankings. Above 30 you are in the high range. Above 35 you are in the excellence range.

For Politecnico di Milano, the situation is different: the TOLC-I score is converted to a 100-point scale according to specific tables in the call for applications, and the minimum eligibility threshold is 30/100. For early admission from the fourth year, at least 75/100 is needed.

Mathematics: the heart of the TOLC-I

With 20 questions out of 50 and 50 minutes out of 110, mathematics weighs more than any other section. If you do poorly here, you cannot recover elsewhere.

The CISIA syllabus topics essentially cover the math programme from the first 4 years of scientific high school:

Arithmetic and algebra — number properties, powers, radicals, algebraic expressions, first and second degree equations and inequalities, linear systems, polynomials. This sounds like third-year stuff, and it is. But "knowing" does not mean "solving in 2 minutes under pressure." Speed is trained, and if you have structural gaps, a course of targeted math tutoring can fill them in reasonable time.

Geometry — Euclidean geometry (theorems on triangles, circles, areas), analytic geometry (line, parabola, circle in the Cartesian plane, distance between points). Analytic geometry questions are among the most frequent and most frequently missed: they require both graphical understanding and precise calculation.

Functions — domain, graphs of elementary functions (linear, quadratic, exponential, logarithmic, trigonometric), function composition, graph interpretation. This is not about calculating limits or derivatives — we are still in "pre-analysis" functions. But reading a graph correctly and quickly is a skill that must be trained.

Trigonometry — sine, cosine, tangent functions, fundamental identities, trigonometric equations. You don't need to know all the product-to-sum formulas, but fundamental identities and values of notable angles must be automatic.

Statistics and probability — basic concepts: mean, median, mode, simple probability, elementary combinatorics. Few questions, but often free points for those who know them.

The most important advice for the math section: don't waste time on hard questions in the first 30 minutes. Answer everything you can do first, then return to the tough ones. With 20 questions and 50 minutes, you have an average of 2 minutes and 30 seconds per question — but some you solve in 30 seconds and others take 5 minutes. Time management is half the battle.

Logic: less studying, more training

The logic section evaluates reasoning ability, not knowledge. There is no "programme" to study in the traditional sense — but there is a way to train that makes a difference.

Logic questions include deductive reasoning (if A then B, not B, therefore not A), set relationships, numerical and letter sequences, quantitative problems and questions requiring analysis and rational choice.

The trick — which is not really a trick — is familiarity. Someone who has already seen 200 logic questions immediately recognises the "type" of question and knows which strategy to apply. Someone facing 10 for the first time on test day wastes precious minutes figuring out what is being asked.

A practical tip: learn to take notes while reasoning. Draw diagrams, write down relationships, sketch frameworks. The scratch paper is your main tool in the logic section.

10 questions in 20 minutes = 2 minutes per question. That sounds like a lot, but logic questions have long texts. Careful reading — without skipping words — is essential.

Sciences: high school physics and chemistry

The TOLC-I sciences section has 10 questions in 20 minutes: approximately 70% physics (mechanics, thermodynamics, optics, electromagnetism) and 30% chemistry (atomic structure, bonds, reactions, pH). No calculator is allowed — questions require concept understanding, not complex calculations.

The sciences section covers physics (approximately 70% of questions) and chemistry (approximately 30%). Topics are from high school:

Physics: mechanics (forces, work, energy, Newton's laws), geometric optics (reflection, refraction, lenses), thermodynamics (temperature, heat, ideal gases), electromagnetism (Coulomb's law, current, Ohm's law, magnetic field).

Chemistry: atomic structure, periodic table, chemical bonds, stoichiometry, chemical reactions (redox, combustion), basic organic chemistry, pH and solutions.

The problem many students have with this section is that fifth-year physics topics (waves, relativity, modern physics) are not needed — but third and fourth-year topics have been forgotten. If you take the TOLC-I in your fifth year or after graduation, you may discover that mechanics or geometric optics are rustier than you thought.

No calculator is needed (none is allowed), so questions are designed to be solvable with simple calculations. The focus is on understanding concepts, not numerical calculation ability.

Verbal Comprehension: the underestimated wild card

10 questions in 20 minutes on texts to read and analyse. Many STEM students consider this the "easy" section and don't prepare for it. And it is true that scores here are generally higher — but it is also the section where you can score 10/10 with little effort if you train, gaining points that would cost you hours of extra study in mathematics.

The questions require identifying a passage's meaning, identifying the main argument, recognising logical implications in the text, and distinguishing facts from opinions. The key is to read the text once carefully, then answer. Rereading everything from the beginning for each question is the surest way to run out of time.

English: it doesn't count (but almost)

The English section (30 questions, 15 minutes) does not affect the main score. There is no penalty for wrong answers. So why mention it?

Because some universities use it for assigning language OFAs. Politecnico di Milano, for example, assigns an English OFA if you answer fewer than 24 questions out of 30 correctly. It is not dramatic, but it is a hassle to clear during the first year.

Also, English comes after the four main sections. If you arrive drained after 110 minutes of testing, these last 15 minutes can feel endless. Factor in this mental fatigue when planning your preparation.

How to organise preparation

The time needed depends on your starting level: from 2-4 weeks for those with a solid foundation who just need to familiarise with the format, up to 3-4 months for those with significant math gaps. The key is alternating topic study with timed simulations, not doing all of one then all of the other.

There is no universal plan because it depends on your starting point. But there are principles that work for everyone.

If you have 3+ months

The ideal situation. You can afford to build the foundations before moving to simulations.

Phase 1 — Diagnosis (week 1). Take a full simulation under real conditions — timed, no interruptions, no help. The result doesn't matter: it is to understand where you stand. Which section is weakest? Where do you waste the most time? Where do you make careless errors vs. knowledge errors?

Phase 2 — Study by topic (weeks 2-8). Work on topics one at a time, starting from the weakest. Mathematics deserves at least 50% of total time. After each topic, do specific exercises — not full simulations, but blocks of 10-15 questions on that theme. The goal is to fill gaps, not accumulate simulations.

Phase 3 — Full simulations (last 4-6 weeks). Now yes: full simulations, timed, under conditions as close as possible to the real test. After each simulation, analyse errors — not just "which answer was right" but "why I got it wrong." Knowledge error? Calculation? Time? Reading? Each type of error requires a different correction.

If you have 1 month

Less margin, more intensity. Skip the extensive topic-by-topic study phase — focus on areas where you can gain the most points in the least time. Usually these are logic and verbal comprehension (quickly improvable with practice) and the math topics you almost know but don't master.

Take a diagnostic simulation immediately, identify the 3 weakest areas, work on those and nothing else. Don't try to cover the entire programme — you don't have time. Better to be solid on 80% of the syllabus than fragile on 100%.

If you have less than 2 weeks

Honestly? Consider whether it makes sense to show up now or wait until the following month. Two weeks are not enough to build knowledge that isn't there, but they are enough to familiarise yourself with the test structure, time management and response strategy. If your base level is good and the problem is just that "you've never seen a TOLC-I," then two weeks of intensive simulations can make a real difference.

The difference between "doing exercises" and "actually preparing"

Actually preparing means timed simulations under real conditions, systematic error analysis (not just the score), difficulty adapted to your level and tracking progress week by week. Downloading PDFs and solving them without time pressure does not build the skills needed for the test.

This distinction is the core of everything. Downloading PDFs of old tests and solving them on the weekend is not preparation — it is entertainment with a clear conscience.

Actually preparing means:

Simulations under real conditions. Timer, no phone, no notes. If you take the test from home (TOLC@CASA), practice in the same environment with the same computer. If you take it on campus, get used to working without distractions for 2 consecutive hours.

Error analysis, not just results. The simulation score is a number — what matters is why that number is what it is. A spreadsheet with simulation date, score by section, error types and wrong topics is worth more than 10 more simulations done without analysis.

Difficulty adaptation. If you always do simulations that are too easy, you don't improve. If you always do simulations that are too hard, you get demoralized. The level must follow your progress. Adaptive simulations — those that adjust difficulty based on your answers — are the most efficient way to train, and this is the principle on which we built the Up to Ten test platform: the same IRT (Item Response Theory) logic used in major adaptive tests such as the GMAT and SAT.

Tracking progress over time. Not "I feel like I've improved" — numbers, week by week, section by section. If after 3 weeks of study your math section is still at 10/20, something in the strategy isn't working and needs to change. We track everything in Up to Connect — every simulation, every weak area, every improvement — but even a well-organised Google Sheet works. The important thing is not to go by feeling.

TOLC@CASA or TOLC@UNI: which to choose

The TOLC-I can be taken at a university venue (TOLC@UNI) or from home (TOLC@CASA) with webcam proctoring. For the first attempt we recommend the in-person mode: controlled environment, fewer technical risks, no connection issues. The at-home mode is more convenient but adds variables outside your control.

The TOLC-I can be taken in two modes:

TOLC@UNI — in person, at university classrooms. You go with your ID and registration receipt. The advantage is that the environment is controlled and structured: fewer distractions, fewer technical risks. The disadvantage is that you have to travel, and "exam room" anxiety is real.

TOLC@CASA — remotely, from your computer, monitored via webcam and smartphone. The proctoring platform uses Webex, and you must install the Horizon app from the CISIA reserved area by the day before the test. The advantage is convenience. The disadvantage is that technical problems (connection dropping, software not starting, non-compliant room) can ruin the test.

Our advice: if you can, take the first attempt on campus. Fewer variables outside your control. For subsequent attempts, the at-home option becomes more manageable because you already know what to expect from the test.

The mistakes we see most often

The 5 most common TOLC-I mistakes are: getting stuck on the first hard question instead of skipping it, not practising with a timer, ignoring the sciences section (20% of the score), answering randomly without eliminating options, and preparing only with theory without realistic simulations. These are strategy mistakes, not knowledge ones — and they are fixable.

After preparing hundreds of students, the recurring mistakes can be counted on one hand:

1. Spending too much time on the first hard question. Skip it, move on, come back later. Every minute lost on a 1-point question is a minute stolen from three 1-point questions you would have solved.

1. Not training with a timer. Being able to solve a question in 10 minutes is useless if you have 2 and a half. Speed is not a talent — it is a skill that is trained.

1. Ignoring the sciences section. "It's only 10 questions." Yes, but they are 20% of the score. 3 extra points in sciences are much easier to gain than 3 extra points in mathematics.

1. Answering everything even when you don't know. The -0.25 penalty is small, but on 10 random answers you statistically lose 2 net points. Better to leave blank if you cannot eliminate at least one option.

1. Preparing only with theory. The TOLC-I is not a university exam. It is not enough to "know" the topics — you need to apply them under time pressure in a multiple-choice format. Only realistic simulations build this skill.

Official resources and where to find them

The essential resources for TOLC-I preparation are the CISIA website (regulations, syllabus, official simulations), your specific university's call for applications (thresholds, dates, criteria), and CISIA MOOCs for review. The free CISIA simulations are excellent for familiarizing with the format but have a limited database.

CISIA website — cisiaonline.it: regulations, syllabus, date calendar, practice area with official simulations. It is the mandatory starting point.

CISIA practice tests — CISIA offers free simulations in the practice area. Take at least 2-3 to understand the format. They are not sufficient for complete preparation (the database is limited), but they help build familiarity.

University call for applications — each university publishes its own call with minimum scores, dates, ranking criteria and specific rules. Read it in full, including the footnotes.

CISIA MOOCs — free online review courses on mathematics, logic and sciences. Useful as supplementary material, not as a preparation base.

When self-preparation is not enough

Structured support makes a difference when math gaps are deep (trigonometry, analytic geometry), when your score is not improving despite simulations, or when you must prepare for the TOLC-I and final exams simultaneously. In these cases a tutor who knows the test identifies the problem in time frames that would take weeks on your own.

Many students prepare on their own with good results. But there are situations where structured support makes a difference:

• The gaps are deep — you don't remember trigonometry, analytic geometry has always been difficult, the equation of a line confuses you. Starting from zero on your own on these topics takes time you may not have.
• You do simulations but the score doesn't improve — you keep making the same mistakes but can't figure out why.
• The TOLC-I is not your only commitment — you are preparing for finals, have other subjects, and can't manage everything on your own.
• You need adaptive simulations — those that adjust difficulty to your level, not those that give you the same 50 questions as everyone else.

At Up to Ten TOLC-I preparation works like this: a dedicated tutor who knows the test builds a personalised plan around your specific gaps, and our adaptive simulation platform lets you train with tests that adapt to your level — the more you get trigonometry wrong, the more trigonometry questions you receive, until that gap is closed. Everything tracked, everything measurable.

FAQ — Frequently asked questions about the TOLC-I

How many times can I take the TOLC-I? Once a month, with no limit on total attempts. You can book the next attempt from the day after taking the test.

How much does the TOLC-I cost? The fee is approximately €30 per attempt (some venues may charge a slightly different amount). It is non-refundable, but in case of absence you receive a credit usable by December 31.

Is the TOLC-I score valid for all universities? Yes. A single TOLC-I can be used for admission to multiple degree programmes and universities, as long as they require the same type of test. Validity is generally two calendar years (always check the specific call for applications).

Can I use a calculator? No. No calculation tools are allowed. Questions are designed to be solvable without a calculator.

What happens if I don't meet the minimum threshold? It depends on the university. In open-admission programmes, you generally enrol anyway but with an OFA to fulfil during the first year. In limited-enrolment programmes, you may not make the ranking.

Is it worth taking the TOLC-I in the fourth year of high school? Yes, for two reasons: you understand your real level with a year's advance, and some universities (like Politecnico di Milano) offer early admission for those who achieve high scores from the fourth year.

How do I prepare for the logic section if "there's nothing to study"? There absolutely is — not facts, but method. You need to do hundreds of logical reasoning questions to recognise patterns and speed up responses. Logic is trained, not improvised.
