TOLC-I vs TOL Politecnico: How to Choose

The TOLC-I is the national CISIA test: 50 questions in 110 minutes, with separate sections for mathematics, logic, sciences and reading comprehension. The TOL is the Politecnico di Milano test: 65 questions in 100 minutes, with logic-mathematics-statistics in a single block and physics as a separate section (no chemistry). The Politecnico accepts both, but they require different strategies.

This is one of the questions we hear most often from those wanting to get into Engineering at the Politecnico di Milano: is the TOL or the TOLC-I better? The answer isn't as obvious as it seems, and it depends on factors that go beyond the test structure.

In this guide we place the two tests side by side: structure, sections, timings, scoring, available attempts, costs, and above all the practical implications of each choice. By the end you should have enough to go on to decide -- or to realise that perhaps the right answer is "both."

The Numbers, Upfront

The main differences between TOLC-I and TOL: the TOLC-I has 50 questions in 110 minutes with separate sections and can be retaken once per month; the TOL has 65 questions in 100 minutes with logic-mathematics-statistics in a single block and can be taken a maximum of 2 times per year. The Politecnico accepts both but they require different strategies.

Before getting into the detail, here's the direct comparison. Come back here whenever you want to refresh your memory.

From this table alone you can see these aren't the same test with a different name. The structural differences change the preparation, the strategy during the test and even the risk-benefit calculation of each choice.

How the TOLC-I Is Structured

The TOLC-I has 50 questions in 4 separate sections with dedicated time: mathematics (20, 50 min), logic (10, 20 min), sciences with physics and chemistry (10, 20 min), reading comprehension (10, 20 min). It can be taken once per month with no annual limit, costs approximately 30 euros, and is valid for nearly all Italian universities.

The TOLC-I (Test Online CISIA for Engineering) is the national test administered by CISIA, the Inter-University Consortium for Integrated Access Systems. It is accepted by dozens of universities across Italy.

50 questions, divided into 4 sections with dedicated time for each:

• Mathematics: 20 questions, 50 minutes
• Logic: 10 questions, 20 minutes
• Sciences (physics + chemistry): 10 questions, 20 minutes
• Reading Comprehension: 10 questions, 20 minutes

Then there's the English section (30 questions, 15 minutes), which doesn't count towards the main score but can assign a language OFA.

Total: 110 minutes for the main part + 15 for English. Maximum score: 50 points.

You can take it once per month, with no annual limits. Cost: approximately 30 euros per attempt. Available both at university venues (TOLC@UNI) and from home (TOLC@CASA).

How the Politecnico TOL Is Structured

The TOL has 65 questions with logic-mathematics-statistics in a single block (25 questions, 65 min), reading comprehension (5, 10 min), physics without chemistry (5, 10 min), English (30, 15 min). It takes place remotely only, can be taken a maximum of 2 times per year, costs 35 euros, and is valid only for Politecnico di Milano.

The TOL (Test On Line) is the specific admission test for Politecnico di Milano. It is not managed by CISIA -- the university administers it directly.

65 questions, distributed as follows:

• Logic, Mathematics and Statistics: 25 questions, 65 minutes
• Reading Comprehension: 5 questions (on 1 passage), 10 minutes
• Physics: 5 questions, 10 minutes
• English (TENG): 30 questions, 15 minutes

Total: 100 minutes. Final score expressed on a base of 100, obtained through a weighting system by section -- not all questions count equally.

The TOL takes place exclusively remotely, from your computer, with supervision via SEB software (Safe Exam Browser) and a virtual room.

For the 2026/27 academic year, you can take the TOL a maximum of 2 times: one per time window. If you don't show up for a booked test, it counts as taken. Cost: 35 euros per attempt.

There is also the early TOL for those in the fourth year of high school, with dedicated windows and the possibility of early admission with a score of 75/100 or above.

The 6 Differences That Really Matter

The 6 key differences between TOLC-I and TOL are: mathematics and logic separate vs combined, physics with chemistry vs physics only, 10 questions vs 5 for reading comprehension, linear vs weighted scoring, nearly unlimited attempts vs max 2, universal validity vs PoliMi only. The right choice depends on your strengths and admission strategy.

1. Mathematics and Logic: Separate or Combined

This is the most important difference for preparation.

In the TOLC-I, mathematics and logic are two distinct sections. You have 50 minutes for 20 mathematics questions, then 20 minutes for 10 logic questions. You can focus on one type of reasoning at a time.

In the TOL, logic, mathematics and statistics all go into a single block of 25 questions in 65 minutes. The transition is continuous -- you might find yourself solving a quadratic equation, then a logical reasoning question about sets, then a statistics question, then algebra again. A different kind of mental flexibility is needed.

The TOL's single block is longer (65 straight minutes) but also more demanding from a cognitive standpoint: there's no "breather" between sections. Those who are strong in mathematics but weak in logic (or vice versa) can manage time separately in the TOLC-I -- in the TOL, you can't.

2. Physics: Standalone in the TOL, Included in Sciences in the TOLC-I

In the TOLC-I, the Sciences section mixes physics and chemistry in 10 questions (with physics accounting for about 70%). You need to know both.

In the TOL, physics has its own standalone section of 5 questions in 10 minutes. And chemistry? It's not there. Zero chemistry questions in the TOL.

For those who dislike chemistry, the TOL is objectively more friendly. For those who do well in chemistry and would use it to compensate for weaknesses in physics, the TOLC-I offers more flexibility.

3. Reading Comprehension: 10 Questions vs 5

The TOLC-I dedicates 10 questions and 20 minutes to reading comprehension -- 20% of the total score. It's a section where many STEM students can score "easy" points with a bit of practice.

The TOL has only 5 (on a single passage) in 10 minutes. Fewer opportunities to earn "compensating" points if the technical sections go badly.

4. Scoring: Linear vs Weighted

The TOLC-I has linear scoring: +1 for correct, -0.25 for incorrect, 0 for omitted. Maximum 50. Every question is worth the same.

The TOL uses a section weighting system. The logic-mathematics-statistics block weighs much more than physics or reading comprehension. The final score is on base 100, but it's not a simple proportion -- it depends on how the PoliMi weights each area.

In practice: in the TOL, doing well in mathematics and logic counts more than in the TOLC-I, where the 4 sections have weights proportional to the number of questions.

5. Attempts: Nearly Unlimited vs Max 2

The TOLC-I can be retaken once per month, with no annual limit. You can take it in February, then March, then April -- keeping the best score each time. This flexibility is enormous: you can use the first attempts as low-pressure "real simulations."

The standard TOL can be taken a maximum of 2 times per year: one per window. Two chances, period. If you fail the first and the second, it's over for that year.

This radically changes the approach. With the TOLC-I you can afford to try "to see what it's like." With the TOL, every attempt is precious.

6. Validity: Universal vs Specific

A TOLC-I taken in Milan is also valid for Turin, Bologna, Rome, Naples -- wherever the university accepts it.

A TOL is valid only for Politecnico di Milano.

If your only option is PoliMi, this doesn't affect you. But if you want to keep multiple paths open -- and it's almost always advisable -- the TOLC-I gives you much more coverage.

The Politecnico Accepts Both: How It Works

Politecnico di Milano accepts TOLC-I, TOL, CEnT-S and SAT. If you choose the TOLC-I, the score is converted to base 100 according to specific tables. The minimum eligibility threshold is 30/100 for all tests; for early admission from fourth year of high school you need at least 75/100. You must register the result in the Online Services by the call deadlines.

The 2026/27 Politecnico di Milano application accepts four admission tests:

• TOL (PoliMi's own test)
• TOLC-I (national CISIA test)
• CEnT-S (CISIA standardised test for the scientific area -- recent addition)
• SAT (international test)

If you choose the TOLC-I, your score is converted to base 100 according to tables defined by the Politecnico. The conversion takes into account section scores and statistical parameters -- it's not a simple proportion.

The minimum eligibility threshold is 30/100 (rounded to the nearest integer), regardless of which test you chose. For early admission from the fourth year of high school, you need 75/100 or above.

An important detail: if you take the TOLC-I for PoliMi, you must register the result in the Politecnico's Online Services by the deadlines in the call for applications. It doesn't happen automatically. If you forget to register it, the score won't be considered -- even if you took the test. Read the call, note the deadlines.

So Which Is Better?

The TOL is better if you are only targeting PoliMi, chemistry penalizes you, or you are strong in mathematics and logic (the weight is higher). The TOLC-I is better if you want to keep multiple universities open, want more attempts (1 per month vs 2 per year), or prefer to take the test in person. The best strategy for many is to take both — 80% of preparation is shared.

There is no universal answer, but there are situations where one choice is clearly better than the other.

The TOL is better if...

You're only targeting Politecnico di Milano. If PoliMi is your only choice and you're not interested in having a "plan B" at other universities, it makes sense to prepare directly for the test that university designed. The TOL is calibrated to PoliMi faculty expectations -- in theory, those who do well on the TOL are the ones PoliMi wants.

Chemistry gives you trouble. It's not in the TOL. If chemistry is your weak point and in the TOLC-I it would cost you 2-3 points in the Sciences section, the TOL eliminates the problem at its root.

You're strong in mathematics and logic. The single 25-question block with high weight rewards those who are solid on these topics. If mathematics and logic are your strengths, the TOL's weighting system amplifies your advantage.

The TOLC-I is better if...

You want to keep multiple universities open. This is the strongest reason. A TOLC-I gives you access to PoliMi (with conversion) and simultaneously to Turin, Bologna, Padua, Rome, Naples -- any university that accepts it. With a single test you cover everything.

You want more attempts. The difference between "2 attempts per year" and "1 per month with no limits" is enormous. You can take the TOLC-I in February as a trial, then retry in March improved, then in April -- building the score progressively. With the TOL you have two chances and that's it.

Reading comprehension is your ace. 10 questions versus 5 means double the opportunities to score points in an area that for many STEM students is the "easiest" to improve.

You want to take it in person. The TOL is remote only. If you prefer a controlled environment without the risk of technical problems at home (connection dropping, software not starting, flatmate ringing the doorbell), the TOLC-I in TOLC@UNI mode gives you this option.

The "Both" Strategy

Many students -- and we often recommend it -- take both the TOLC-I and the TOL. They're not mutually exclusive: you can take the TOLC-I to have a safety score valid everywhere, and the TOL to aim for the maximum at PoliMi.

80% of the preparation is shared -- mathematics, logic, reading comprehension, English. The specific differences (chemistry vs no chemistry, statistics more prominent in the TOL, section weighting) are managed with a few targeted practice sessions in the final weeks.

The additional cost is modest (30 euros + 35 euros = 65 euros for one attempt of each) and the advantage of having two parallel options can make the difference between getting in and not getting in.

How Preparation Changes

80% of preparation is shared (mathematics, logic, reading comprehension, English). The specific differences: for the TOLC-I add chemistry and managing 4 separate sections; for the TOL add statistics, train cognitive endurance for the 65-minute single block, and use simulations in the specific format (DOL, Politest).

If you've decided which test to take -- or if you're taking both -- here's what to focus on.

Common Preparation (valid for both)

Mathematics: algebra, equations and inequalities, analytical geometry (line, parabola, circle), functions, trigonometry. This block is the core of both the TOLC-I and the TOL. This is where the game is played -- and if you have gaps, a course of targeted mathematics tutoring is the fastest way to fill them.

Logic: deductive reasoning, set relations, sequences, quantitative problems. Logic is trained through practice -- hundreds of questions are needed to recognise patterns.

Reading comprehension: careful reading, identifying the main argument, distinguishing facts from opinions. Quick training, nearly immediate results.

English: doesn't affect the main score in either test, but can assign OFAs. A review of grammar and written comprehension at B1-B2 level is sufficient.

Specific Preparation for the TOLC-I

Sciences: physics (mechanics, optics, thermodynamics, electromagnetism) + chemistry (atomic structure, periodic table, reactions, stoichiometry, pH). 10 questions where chemistry accounts for about 30%.

Time management: 4 separate sections with a dedicated timer for each. Train to respect each section's limits without going over.

Specific Preparation for the TOL

Statistics: mean, median, mode, probability, combinatorics. In the TOLC-I statistics is marginal; in the TOL it's part of the main block.

Physics as a standalone section: only 5 questions in 10 minutes, but without chemistry. You can focus study on mechanics, thermodynamics, optics and electromagnetism without spending time on chemistry.

Cognitive endurance: the logic-mathematics-statistics block lasts 65 straight minutes. Simulate this duration during preparation -- never break it into shorter chunks. Our TOL preparation path is structured precisely to train this endurance with simulations in the specific Politecnico format.

TOL-format simulations: PoliMi makes available the DOL (Demo On Line) and the Politest. Use them: the format is specific and familiarity with the interface matters. For adaptive simulations that track progress and adapt to your level, the Up to Ten platform covers both the TOLC-I and TOL formats.

The CEnT-S: The Third Option

The CEnT-S (CISIA test for the scientific area) has 55 questions in 5 sections, but PoliMi considers only Mathematics, Reasoning and Physics — not Biology and Chemistry. It is a relatively new option with conversion tables still limited. It makes sense if you need it for another university and want to use the same result for PoliMi as well.

Starting with the 2026/27 application, the Politecnico also accepts the CEnT-S (CISIA test for the scientific area). It has 55 questions divided into 5 sections: Mathematics, Reasoning on texts and data, Biology, Chemistry, Physics.

For converting the CEnT-S into a score on base 100, PoliMi does not consider the Biology and Chemistry sections -- only Mathematics, Reasoning and Physics. It's a relatively new and less established option, so conversion tables and practical experience are still limited.

If you're already taking the TOLC-I or the TOL, the CEnT-S adds complexity without a clear advantage. It may make sense if you need the CEnT-S for another university and want to use the same result for PoliMi as well.

A Note on OFAs at the Politecnico

Since 2024 the Politecnico di Milano has eliminated mathematics OFAs — there is no longer the risk of being stuck due to a mathematics OFA. The only remaining OFA is the English one: if you answer fewer than 24 questions correctly out of 30 in the English section, you are assigned a language OFA to complete during the first year.

Significant update since 2024: the Politecnico di Milano has eliminated mathematics OFAs. In the past, a low score in the mathematics section assigned you an additional formative obligation that blocked your academic progression. That's no longer the case.

The only remaining OFA is the English language one: if in the English section (TENG in the TOL, English section in the TOLC-I) you answer fewer than 24 questions correctly out of 30, you're assigned an English OFA to complete during the first year.

This doesn't mean mathematics doesn't matter -- it very much does for the ranking. But there's no longer the risk of being "stuck" due to a mathematics OFA.

The SAT: The Outsider

The SAT is accepted by PoliMi with a minimum threshold of 620/800 in each section (Reading/Writing and Mathematics). It makes sense almost exclusively for students with an international background (American, British, IB schools) who are already familiar with the format. For those who attended an Italian liceo, preparing for the SAT requires disproportionate effort compared to the TOLC-I or TOL.

The PoliMi application also mentions the SAT (Scholastic Assessment Test) as an alternative. It's the standard American test, with Reading/Writing and Mathematics sections. To be valid at PoliMi you need at least 620/800 in each section.

It's an option that makes sense almost exclusively for students with an international background (American, British, IB schools) who are already familiar with the format. For those who attended an Italian liceo, preparing for the SAT requires a disproportionate effort compared to the TOLC-I or TOL -- the structure is completely different, the test is in English, and the Reading/Writing section has no equivalent in Italian education.

How to Choose: The Practical Checklist

The choice depends on 6 factors: if PoliMi is your only choice (TOL), if chemistry penalizes you (TOL eliminates it), if you want more attempts (TOLC-I), if you prefer testing in person (TOLC-I only), if you are strong in mathematics/logic (TOL amplifies the advantage), and if you have time and budget for both (take both — 80% of preparation overlaps).

1. Is PoliMi your only choice? Yes: consider the TOL. No: take the TOLC-I (covers more universities).
2. Does chemistry penalize you? Yes: the TOL eliminates it.
3. Do you want more than 2 attempts? The TOLC-I gives you one per month.
4. Do you prefer to take the test in person? Only the TOLC-I offers this option (TOLC@UNI).
5. Are you strong in mathematics/logic? The TOL amplifies this advantage with section weighting.
6. Do you have the time and budget for both? Take both. The preparation is largely overlapping.

There is no "easier" test in absolute terms. There is the test best suited to your situation, your strengths and your admission strategy.

FAQ

If I take both the TOLC-I and the TOL, which score does the Politecnico use? The better of the two (after converting the TOLC-I to base 100). You can register both in the Online Services and the system takes the highest.

Is a TOLC-I taken at another venue valid for PoliMi? Yes. The TOLC-I is national: you can take it in Naples and use the result for Politecnico di Milano. But you must register it in the PoliMi Online Services by the call deadlines.

Can I take the early TOL in the fourth year and the TOLC-I in the fifth? Yes. They are independent tests with different calendars. You can use the early TOL to try for early admission (75/100 or above) and the TOLC-I in fifth year as a backup plan.

Is the TOL harder than the TOLC-I? It's not "harder" in absolute terms, but it has less margin: less time per question, fewer attempts, fewer sections to compensate in. For those well prepared in mathematics and logic, the TOL can feel more natural. For those with a more balanced profile, the TOLC-I offers more recovery possibilities.

Does converting the TOLC-I score to base 100 penalize me? Not necessarily. The conversion takes into account statistical parameters and isn't a simple proportion. In some cases a good TOLC-I score can convert better than expected -- but the exact criteria change from year to year. The only certainty is that a high TOLC-I score converts well regardless.

How much does it cost to prepare for both tests? In terms of study, the additional cost is minimal: 80% of preparation is shared. In financial terms, we're talking about 65 euros for one attempt of each (30 + 35 euros). If you consider that each failed attempt costs a month of waiting (TOLC-I) or half your annual chances (TOL), investing in preparation is almost always more cost-effective than multiplying attempts.
