TOLC-I: Structure, Score and Sections

The TOLC-I has 50 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), plus 30 English questions. Scoring: +1 correct, -0.25 incorrect, 0 omitted. National average: 20-22 out of 50.

When I took my first TOLC-I, the thing that caught me most off guard wasn't the questions — it was the structure. I didn't know the time was divided by section, I didn't know I couldn't go back, and I hadn't calculated properly how much time I had per question. I learned the hard way that knowing the test structure before sitting down to study isn't a detail — it's the prerequisite.

This guide takes the TOLC-I apart piece by piece: real timings, scoring with all its strategic implications, and what to concretely expect in each section. If you're looking for a complete overview of preparation, start with the complete TOLC-I guide.

The Structure in Numbers

The TOLC-I has 50 questions in 110 minutes divided into 4 sections with dedicated time: mathematics (20 questions, 50 min), logic (10, 20 min), sciences (10, 20 min), reading comprehension (10, 20 min). Plus 30 English questions in 15 minutes that do not count towards the main score. Time per section is not cumulative.

All updated details are on the official CISIA page with structure and syllabus.

Every question has 5 answer options, of which only one is correct.

Section 1 — Mathematics

20 questions in 50 minutes (2.5 min/question) — the section with the most time per question, but also the most demanding.

This average is deceptive. Some arithmetic or statistics questions are solved in 30 seconds. Some analytical geometry or trigonometry problems require 4-5 minutes. The real exercise isn't "knowing mathematics" — it's managing time knowing that the questions aren't all equal.

Topics: arithmetic, algebra, Euclidean and analytical geometry, functions and their graphs, trigonometry, elementary statistics and probability. All within the liceo scientifico programme up to the fourth year. No limits, derivatives, or integrals.

Why it weighs so much: 20 questions out of 50 = 40% of the score. But there's a multiplier effect: many universities set specific thresholds just for mathematics. At Parma you need at least 4/20 in mathematics to avoid the OFA, regardless of the total. At Politecnico di Milano the score conversion heavily penalizes those who do poorly in mathematics. You can't just compensate with other sections — if you have gaps in this section, a course of targeted mathematics tutoring is often the most effective investment.

Section 2 — Logic

10 questions in 20 minutes (2 min/question).

Seems more generous than mathematics, but there's a catch: logic question texts are long. A single question can have a paragraph of premises to read, analyse and deduce the answer from. The 2 minutes include reading time.

Topics: deductive reasoning (syllogisms, logical implications), ordering and membership relations, sequences, quantitative reasoning problems. No formulas are needed — structured reasoning is.

The logic paradox: it's the section where traditional study is least useful, but where specific training makes the biggest difference. A month of practice with logic questions can be worth 3-4 extra points. A month of theory without practice is worthless.

Section 3 — Sciences

10 questions in 20 minutes (typically 7 physics + 3 chemistry).

Sciences cover physics (approximately 70% of questions) and chemistry (approximately 30%). Topics are from the secondary school programme:

Physics: mechanics (forces, work, energy, Newton's laws), geometrical optics, thermodynamics (gases, heat, temperature), electromagnetism (Coulomb, Ohm, fields).

Chemistry: atomic structure, periodic table, chemical bonds, reactions, basic stoichiometry, pH, elementary organic chemistry.

The real problem: it's not that the topics are hard — it's that they've been forgotten. If you take the test at the end of fifth year or after graduation, you'll discover that the fluid mechanics from third year is rustier than you thought. The review needs to be planned.

Calculators are not permitted. Questions are constructed with "convenient" numbers — but you need to be comfortable with mental calculations and quick estimates.

Section 4 — Reading Comprehension

Reading comprehension: 10 questions in 20 minutes (2 min/question).

Texts to read, questions about meaning, main argument, explicit and implicit implications. It doesn't require specific knowledge — it requires attention and a reading method.

On average it's the section with the highest scores. Many STEM students ignore it in preparation, and indeed those who read carefully and reason in an orderly way pass it without problems. But be careful: "easy" doesn't mean "free." Getting 2-3 questions wrong here due to rushing is a shame, because those are points that in mathematics would cost you much more effort.

Strategy: read the text once, carefully. Don't reread everything for each question — you have the 2 minutes counted and going back to the beginning of the text each time eats your time.

Section 5 — English (separate)

30 questions in 15 minutes (30 seconds per question — very fast pace). The English section does not affect the admission score. +1 for correct, 0 for incorrect or omitted (no penalty). So why mention it?

Because some universities use it for language OFAs. Politecnico di Milano assigns an English OFA below 24 correct answers out of 30. It's not dramatic, but it's an annoyance during the first year.

And because it arrives after 110 minutes of testing. Mental fatigue is real.

The Scoring System in Detail

The TOLC-I awards +1 point for a correct answer, 0 for unanswered, -0.25 for incorrect. Maximum score is 50, theoretical minimum is -12.5, national average is approximately 20-22. In the English section there is no penalty for wrong answers. The -0.25 penalty makes random guessing neutral, but answering is worth it if you can eliminate at least one option.

Maximum score: 50 (all correct). Theoretical minimum score: -12.5 (all incorrect). National average score: approximately 20-22.

To learn how to read your result in detail, consult the guide on how to view your TOLC result.

The Mathematics of the Penalty

The -0.25 penalty with 5 options makes random guessing statistically neutral. The calculation: with 5 options, the probability of guessing correctly is 1/5 = 0.2. The expected value of a random answer is: (0.2 x 1) + (0.8 x -0.25) = 0.2 - 0.2 = 0.

This means that guessing randomly doesn't hurt you on average. But "on average" is a dangerous phrase with 50 questions. In practice:

• If you can exclude 1 option (4 remaining): expected value = (0.25 x 1) + (0.75 x -0.25) = +0.0625. It's worth answering.
• If you can exclude 2 options (3 remaining): expected value = +0.167. Definitely worth it.
• If you have no idea at all: expected value = 0. You don't lose, but you don't gain. We recommend leaving it blank only in this case, to avoid variance — the risk that bad luck turns an average 0 into a real -0.25.

OFA Thresholds: The Number That Really Matters

If you're not aiming for a programme with limited enrolment, the TOLC-I score doesn't decide whether you get in — it decides under what conditions.

OFA thresholds vary by university. Some examples:

Note: these thresholds change. Some universities update them every year in the call for applications. Always check the current call from your university.

For Politecnico di Milano the situation is different — the TOLC-I score is converted to a base of 100 and determines position in the ranking. There's no OFA threshold in the classic sense; there's an eligibility threshold.

Time Is the Real Enemy

You have approximately 2 minutes per question on average, but some are solved in 30 seconds while others take 4-5 minutes. The time is sufficient only if you manage it: fast first pass on questions you know, second pass on doubts, third pass to decide what to leave blank. The three-pass strategy is the most effective way to maximise your score.

Reread the timing table:

Two minutes per question seems like a lot until you find yourself reading an analytical geometry problem requiring three calculation steps, or a logic question with 8 lines of text. The time is sufficient if you manage it, insufficient if you don't. The best way to train time management is through adaptive simulations that replicate the pressure of the real test.

Three rules:

1. Fast first pass. Answer everything you can do immediately. Mark the questions you'll come back to. In mathematics, a well-executed first pass covers 12-14 questions out of 20 in about 25 minutes.

1. Second pass on doubts. With the remaining time, tackle the marked questions. Start with those where you had a partial idea — where you can at least exclude options.

1. Don't fall in love with a question. If after 3 minutes you haven't even set up the solution, move on. One lost point is better than three lost points from chasing one.

How the Score Is Used

The TOLC-I score is used in different ways: open access with OFA (you get in regardless, but below the threshold you have an additional requirement), limited enrolment (the score determines your ranking position), or early admission from fourth year of high school with high thresholds. The score is generally valid for two calendar years.

Each university uses the TOLC-I score differently:

Open access with OFA — you get in regardless, but below the threshold you have an additional formative obligation (typically a mathematics foundations exam or course to pass within the first year). This is the most common mode.

Limited enrolment — the TOLC-I contributes to the ranking, sometimes as the sole criterion, sometimes combined with the school-leaving exam grade or other factors. Here every point counts.

Early admission — some universities, like the Politecnico, provide early admission windows with high thresholds. Aiming for early admission from the fourth year of high school requires serious preparation but offers an enormous advantage.

Validity — generally the score is valid for two calendar years. If you take the TOLC-I this year, you can use it next year too. This opens up the possibility of taking it at a strategic time — for example in summer, when you have more time to prepare.

FAQ

Are the sections always in the same order? Yes. Mathematics, Logic, Sciences, Reading Comprehension, English. You cannot change the order or return to a previous section.

Can I skip questions and come back to them later? Yes, within the same section. You cannot return to a section already closed.

What happens if I finish a section's minutes early? You move to the next section. You cannot "accumulate" time between sections.

Are the questions the same for everyone? No. The TOLC-I draws from a question bank, so every student receives a different test. The difficulty is calibrated to be equivalent, but the specific questions change.

Is there a difficulty difference between TOLC@CASA and TOLC@UNI? No. The questions come from the same database. The difference is only logistical.
