8 Common TOL Mistakes at Politecnico and How to Avoid Them

The most frequent mistakes on Politecnico di Milano's TOL are not about knowledge but about procedure and strategy: treating it as if it were the TOLC-I (they are different tests), random guessing without knowing the weighted math penalty is -0.65 net points, registering and not showing up (which burns an attempt), forgetting the Early TOL 75/100 shortcut, indicating fewer than 5 preferences, undervaluing the math tiebreaker, not activating SPID/CIE in time, and under-preparing the English section and getting the TENG OFA. They are all fixable — if you know them in advance.

In recent years preparing students for Politecnico di Milano's TOL, I have noticed one thing: most of the mistakes that lose points — or worse, lose an attempt — have nothing to do with math. They have to do with procedure, strategy, and a series of confusions that come from treating the TOL as if it were a test it is not.

This is a specific test: 65 questions in 100 minutes, remote, with a non-linear weighting system and tight attempt rules (max 2, no-show counts as taken). The mistakes we see are often the ones that could have been avoided before the test, by reading the bando carefully. This guide is the distilled version of what we see every year.

In this guide:

• Mistake 1: treating it as if it were the TOLC-I
• Mistake 2: random guessing on the math block

Mistake 1: treating it as if it were the TOLC-I

This is the most frequent confusion, and the one that drives all the others. The TOL is not the TOLC-I. They are different tests, produced by different entities, with different structures, and preparing for one does not equal preparing for the other.

Practical consequences of treating the TOL like the TOLC-I:

• Studying chemistry for the TOL. Wasted time — there is not a single chemistry question on the TOL.
• Training on four-section simulations. Does not prepare you for the 65-minute single block you will face on the TOL.
• Expecting to retake "the next month". You have 2 total attempts, narrow windows, and a no-show counts as taken.
• Expecting linear penalties. On the TOL penalties are section-weighted — raw -0.25 becomes net -0.65 for math questions.

Mistake 2: random guessing on the math block

The TOL applies penalties for wrong answers: -0.25 raw points per wrong answer, 0 for unanswered, +1 for correct. The penalty looks small but with section weights it becomes significant.

This means every wrong answer in the math block costs you 0.65 net points, not 0.25. On a 100-point TOL, one error is worth 0.65% of the total score. A burst of 5 random wrong answers in the math block = -3.25 net points.

Practical rule:

• You know the answer → answer.
• You don't know but can eliminate at least one option → answer.
• You can't eliminate anything and have no idea → leave blank.

On the exact number of answer options per TOL question, check the official simulations (DOL, Politest) for the current format: Politecnico's public documentation does not specify a fixed number of options for all question types. The elimination logic holds regardless — if you reduce the plausible options, answering is statistically advantageous; otherwise, blank.

The TOL is not an arcade quiz — luck works against you when penalties are weighted. Simulations serve this purpose too: figuring out where "I think it's this one" fits and where it belongs in the "leave blank" category.

Mistake 3: no-show — losing an attempt by absence

This is the rule that burns the most attempts each year, and it does so silently. From Politecnico's documentation:

"If you do not show up for a test you are registered for, you will be considered absent and it will count as taken."

Translated: if you register for a test date, pay your EUR 35, and then fail to show up, you have burned one of your two attempts. The reason does not matter (change of mind, technical issue, oversleeping, an unexpected event) — Politecnico counts that test as taken, with a score of zero, and that attempt is gone.

The no-shows we see most:

• "Exploratory" registration. The student registers in March "to see what the first attempt is like", then realizes they are not ready and decides not to show. Result: they have one attempt left, not two, and that attempt is in a narrower window.
• Technical issue. Connection dropping the night before, computer that does not meet requirements, room not compliant with proctoring rules. Verify technical requirements well in advance — not the night before.
• Conflict with school events. Fifth year wrapping up, tests, school trips — check the school calendar carefully before choosing a test date.

Planning rule: do not register for a test you are not sure you will show up to. Better to wait for the next window than to burn one of your two annual attempts on a registration that does not materialize.

Mistake 4: forgetting the 75/100 rule (Early TOL)

This mistake applies only to students in the fourth year of high school — and it is one of the most costly long-term.

The Early TOL is the version of the TOL reserved for penultimate-year students. It has a rule Politecnico explicitly calls a "shortcut": candidates who score ≥ 75/100 (rounded) on the Early TOL may not retake the test but acquire the right to enrol in Italian-language programmes for the 2027/2028 academic year.

What this means concretely: a fourth-year student who scores 75 on the Early TOL has already secured their seat at Engineering at Politecnico for when they graduate in June 2027. No Standard TOL in fifth year to handle alongside the Maturità. No second window in May while preparing the final oral.

The mistakes we see:

• "I'll just take the Standard TOL next year." Without considering that the Maturità in parallel is stress that limits preparation.
• Not knowing the Early TOL exists. Yes, it happens — sounds incredible but many students discover the Early TOL in February of fourth year, when registration is already open and there is no real time to prepare.
• Knowing it exists but not aiming for it. For students who are already strong in math in fourth year, even if they do not hit 75 on the first attempt, they have the most serious diagnostic possible for planning their fifth year.

If you are in fourth year and Engineering at Politecnico is your goal, read the Early TOL guide now, not after the bando.

Mistake 5: indicating fewer than 5 preferences

When registering for the TOL you must indicate up to 5 degree programmes in order of preference. They are binding for the ranking. You can modify them until 23:59 CEST on 18 June 2026.

The mistake we see: students who list 2 or 3 because "I only want Aerospace Engineering, if I don't get in there I'm not interested". It's a choice we understand, but it has consequences. Let's see what happens.

TOL rankings have these possible outcomes for each candidate: ASSIGNED, BOOKED, PENDING, COURSE FULL. When a programme runs out at your top preference, the system scrolls to your next preferences — if you listed them. If you indicated only 2 preferences and both run out, you are out of the ranking even if your score would have been sufficient for other Engineering programmes at Politecnico you did not list.

This means indicating fewer than 5 preferences is a voluntary opt-out. You paid EUR 35 to take the test, studied for months — it makes no sense to self-exclude from programmes you could access. Always indicate 5 preferences in genuine order, even if the fifth is "if nothing else works".

The modifiability until 18 June helps: you have time to think calmly even after seeing how the test went and the ranking trends. But the default must be "always 5 preferences".

Mistake 6: ignoring the math tiebreaker

We repeat it because it is the most strategically important thing about preparation, and almost no one knows it before talking to a tutor.

At equal final ranking score, the first tiebreaker is the Logic-Mathematics-Statistics subscore. This means that, between two students closing at 78.50/100, the one who did better on the math block wins. The second tiebreaker (if the math subscore is also equal) is the younger age.

The mistake we see: students who balance study across sections "because they all matter". Yes — they matter — but math matters twice: for the total score (worth 65%) and for the tiebreaker position.

In competitive limited-place programmes (Aerospace, Computer Science, Management Engineering at Politecnico), the difference between ASSIGNED and PENDING can be one point in the ranking. And that point, at equal final score, is decided on math.

Practical implication: in study-time planning, every extra hour invested in the math section produces double value. Deep dive: TOL Math: Topics, Weights and Strategies.

Mistake 7: not activating SPID/CIE in time

TOL registration is done exclusively through the Politecnico Online Services (`aunicalogin.polimi.it`). To authenticate, you need SPID or CIE — not optional. Without it you cannot even start the registration process.

The mistakes we see:

• Not having SPID or CIE when registration opens. Activating SPID or CIE can take from a few days to several weeks (depending on provider, digital identity, documents). Starting in early February to register for the TOL on 10 February is too late.
• Confusion between "payment" and "registration". Paying the EUR 35 via PagoPA is not registration. Registration is only complete when you finish every step in the Online Services, including authentication via SPID/CIE. Having paid guarantees nothing if you have not closed the procedure.
• Expired SPID or provider issues. Verify your SPID is active and working before starting. SPID technical problems on the day registration closes are a classic — and they are not grounds for deadline extensions.

Solution: activate SPID or CIE in early January, well before TOL registration opens on 1 February. It costs nothing (it is free), you will use it for many other university procedures, and it removes the huge risk of not managing to register due to bureaucratic problems.

Mistake 8: under-preparing English and getting the TENG OFA

The English (TENG) section of the TOL has 30 questions in 15 minutes — 30 seconds per question. It contributes little to the total score (max 10/100), and the typical strategic calculation is "it's not worth much, I'll leave it alone and focus on math".

The problem: there is an operational threshold. If you answer correctly fewer than 24 questions out of 30 in the English section, the TENG OFA kicks in. The TENG OFA (Additional Educational Obligation for English) does not block enrolment, but it carries first-year study-plan limitations:

• You cannot insert additional courses into your study plan.
• You cannot advance courses from subsequent years.
• You cannot submit an autonomous study plan.

The OFA must be cleared during the first year — the exact deadlines for extinguishing it are published by Politecnico on the dedicated study-plan and OFA pages: check the Polimi website for up-to-date deadlines for your enrolment year.

The strategic mistake: treating the English section as a "throwaway section" and arriving at the test without even having looked at the question format. The 24/30 threshold = 80% correct in English. For a student with B1-B2 English, it is reachable with targeted written-comprehension review — but you need to know the format at least.

Practical rule: aim for 27-30/30 correct in the English section, not 24. The difference in net points between 24 and 30 correct is over 2 final points — not marginal.

FAQ

If I made the mistake of listing fewer than 5 preferences, can I fix it? Yes, you can modify preferences until 23:59 CEST on 18 June 2026. Adding the missing preferences is a quick correction — do it as soon as you notice.

If I have an emergency on test day, do I really lose the attempt? Politecnico's rule is clear: "If you do not show up you will be considered absent and it will count as taken." For exceptional situations (certified illness, major events), consider contacting Politecnico Student Services before the test — but the default is that absence burns the attempt. Check the Polimi website for any specific procedures applicable to your situation.

How much is each wrong answer worth in the math section? -0.65 net points per wrong answer in the Logic-Mathematics-Statistics block (weight 2.6 × raw penalty 0.25). Significantly more than the TOLC-I's linear penalty.

Can I choose between TOL and TOLC-I at Politecnico? Yes. Politecnico accepts TOL, TOLC-I, CEnT-S and SAT. If you choose the TOLC-I, the score is converted on a 100-point scale and must reach at least 30 after conversion. Structural comparison: TOLC-I vs TOL Politecnico.

Is the TOL only at home? Yes. The TOL is administered exclusively remotely. There is no in-person mode for Politecnico's TOL — that is one of the differences from the TOLC-I, which can be taken at CISIA centres.

When exactly is the TENG OFA cleared? It must be cleared during the first year of university. The exact deadlines (and what happens if you do not clear it in time) are published by Politecnico on the dedicated study-plan and OFA pages — check the Polimi website for the up-to-date rules for your enrolment year.

How many answer options does each TOL question have? Politecnico's public documentation does not specify a fixed number of options for all question types. Check the official simulations (DOL, Politest) for the current format before the test, so you can plan the elimination strategy.

Can I sit the Early TOL in third year? No. The Early TOL is reserved for students in the penultimate year (fourth year of a five-year secondary school). Third year does not qualify. Details: Early TOL.
