TOLC-I Logic section: what it measures and how to train

Ten questions in twenty minutes: two minutes each, with no formulas to remember. CISIA describes Logic as testing aptitude, not school content, so you train by recognising patterns, not by revising a syllabus.

Each section has its own time limit: finishing early does not give minutes to the others, and you cannot go back to a closed section. Universities use the score with their own thresholds, so read the call of the degree you are applying to.

What this section measures

For Logic and for Reading comprehension CISIA states that they test aptitude and need no specific preparation on a syllabus. In practice the questions are reasoning problems: deductions from rules, counting, ages and work problems, reasoning on sets and quantifiers.

In our bank the questions fall into three families: propositional logic and quantifiers, counting and numerical reasoning, logic problems. Knowing the family of a question is half the solution.

Where points are lost

  • Confusing «only if» with «if»

    «You may book only if you hold a card» says the card is necessary, not that it is enough. It is the most frequent mistake in deduction questions and the one in the solved question below.

  • Solving the wrong question

    In numerical problems the options also contain the value «in five years» or «three years ago». Underline what the question asks and at which moment it refers to before calculating.

How to prepare

  • Train by question family: ten questions in a row on the same pattern teach more than ten scattered ones.
  • Translate the sentences into symbols (if P then Q; Q is necessary for P) before looking at the options.
  • Set a two-minute cap: if a question does not open, move on and come back with the time left.
  • Reread the solutions of the questions you got wrong and note the pattern, not only the result.

Our bank holds 77 questions for this section.

A solved question from our bank

A deduction question with «only if»: the trap is in those two words, not in the content.

Topic: Logica proposizionale e quantificatori · difficulty 2/3

Il regolamento della biblioteca comunale dice: «Un utente può prenotare una sala studio solo se ha una tessera attiva.» Marta ha una tessera attiva. Cosa possiamo concludere con certezza?

  • A Marta può sicuramente prenotare una sala studio
  • B Marta non può prenotare una sala studio
  • C Non si può concludere con certezza se Marta possa prenotare una sala studio, perché la tessera attiva è condizione necessaria ma non necessariamente sufficiente correct
  • D Se Marta non prenota una sala, vuol dire che la tessera non è più attiva
  • E La tessera attiva rende valida automaticamente ogni prenotazione già effettuata

Guided solution

Il trabocchetto è la differenza tra "se" e "solo se".

Passo 1 — Traduco "solo se". "P solo se Q" si formalizza come P → Q, cioè Q è condizione necessaria per P (senza Q, P non può accadere), ma non è detto che basti (non è condizione sufficiente). Qui P = "può prenotare", Q = "ha la tessera attiva": quindi "prenotare → tessera attiva".

Passo 2 — Cosa sappiamo davvero. Sappiamo che Q (tessera attiva) è vera per Marta. Ma da P → Q, conoscere Q vera non permette di dedurre P: potrebbero esserci altre condizioni non menzionate (es. disponibilità della sala, prenotazione entro l'orario) che servono comunque.

Passo 3 — Conclusione. Non possiamo affermare con certezza che Marta possa prenotare. Chi ha scelto «Marta può sicuramente prenotare una sala studio» ha scambiato una condizione necessaria per una condizione sufficiente, un errore molto frequente con "solo se".

The question comes from our own TOLC-I practice bank, written on the CISIA syllabus: it is not a real exam question. The questions in our bank are in Italian, also on this English page.

FAQ

Questions about this section

Do I need to study for TOLC-I Logic?

CISIA describes it as an aptitude section, so there is no syllabus to study: you improve by practising the question patterns.

How many questions and how much time?

Ten questions in twenty minutes, with the same scoring as Mathematics: +1 for a correct answer, 0 for a blank, −0.25 for a wrong one.

Can I come back to Logic after closing the section?

No. Each section has its own time limit and you cannot return to a closed section: the management of the twenty minutes has to be decided inside the section.
