TOLC-S practice test with the real structure of the exam.
Same timing, same 6 sections (including Earth Sciences), same scoring as the CISIA TOLC-S for science, statistics and data science. At the end you get your score out of 55, the breakdown by section and topic, and the correct answer to every question by email — even the ones you skipped; with an account you see them straight away on this page. The step-by-step solution unlocks with your first lesson.
The TOLC-S is the CISIA admission test for science, statistics and data science degrees at Italian universities.
Test in Italian, with an English sectionThe questions are in Italian, as in the real exam; the English section is in English.

Two worked examples from the test
Il compito principale dei globuli rossi (eritrociti) è:
Solution
Gli eritrociti contengono emoglobina, proteina capace di legare reversibilmente l'ossigeno nei polmoni e rilasciarlo nei tessuti periferici; sono privi di nucleo nell'uomo maturo, il che lascia più spazio all'emoglobina stessa. Anticorpi e fagocitosi sono funzioni dei globuli bianchi, la coagulazione coinvolge principalmente le piastrine. Risposta: A.
Due atomi dello stesso elemento con diverso numero di neutroni sono detti:
Solution
Gli isotopi hanno lo stesso numero atomico (stesso elemento, stesso numero di protoni) ma diverso numero di massa perché hanno un numero diverso di neutroni: esempio classico, carbonio-12 e carbonio-14. Gli isomeri sono molecole con la stessa formula ma struttura diversa, gli ioni hanno carica elettrica per perdita/acquisto di elettroni. Risposta: A.

Frequently asked questions.
Is the practice test identical to the real TOLC-S?
It follows the 2026 CISIA structure: 55 questions in 120 minutes across 6 separately timed sections — 20 basic maths, 15 reasoning/problems/reading comprehension, 5 each of biology, chemistry, physics and Earth sciences — plus 30 English questions in 15 minutes, marked separately. Scoring is +1 for a correct answer, −0.25 for a wrong one and 0 for a blank (there is no penalty in the English section). The questions are original, written in the style of the official syllabus — they are not copied CISIA questions.
Is the TOLC-S only for Natural Sciences?
No. The TOLC-S is also required for Statistics, Data Science and Artificial Intelligence — the part many people find out late. Basic maths remains the core of the test in every case.
Is there really an Earth Sciences section?
Yes, and it is often neglected by people preparing: 5 questions on geology, minerals and rocks, plate tectonics, atmosphere and meteorology, hydrosphere and basic astronomy. Few points, but easy to gain with focused revision because the syllabus is narrow.
Can I retake the practice test more than once?
Yes, as often as you like. The questions are drawn at random from a bank of verified questions for each area, so every attempt is a different test. If you close the page halfway through, the test resumes where you left off.
What if my score is low?
That is exactly why the practice test exists: at the end you see the breakdown by section and by topic, so you know where to focus your revision. If you would like a hand, the first call with me is a free diagnostic: we look at the results together and build a plan around your real gaps.
Want to raise your score for real?
The practice test shows you where you lose points; in lessons we work exactly there, on the official CISIA questions, with a timed practice test every 3–4 lessons. Read how the TOLC-S preparation works or start with the free diagnostic call.
