CEnT-S

CEnT-S came into use in November 2025, replacing English TOLC-I, TOLC-E and TOLC-F with a single test. Programmes in engineering, science, biology, pharmacy, economics, psychology and agriculture all accept it.

Because the test is new, most of what circulates online still describes the three exams it replaced. Two rules in particular change how you should sit it, and neither existed in the form candidates are used to.

Structure

Every section allows exactly two minutes per question. Once you leave a section it closes, and time does not carry over, so finishing early forfeits whatever is left of it. The test can only be submitted from the final section.

Scoring, and the quarter-mark penalty

A correct answer is worth 1 point. A blank is worth 0. A wrong answer costs 0.25. Raw scores therefore run from −13.75 to 55, which means a negative score is possible: it indicates answering badly rather than not answering at all.

With five options and a quarter-mark penalty, a blind guess is worth exactly nothing.One time in five you gain a mark. The other four times you lose a quarter.

That is the design, and it is the part almost every other source gets wrong. Random answering neither helps you nor hurts you, so the advice to leave a question blank is not protecting you from anything. What changes the arithmetic is elimination.

The moment you rule out a single option, guessing becomes profitable. So the rule is not when in doubt, leave it blank. It is: eliminate what you can, and answer whenever you have eliminated anything at all. How normalisation is calculated.

What you may bring

No calculator, no formula sheet, no periodic table. Pen and the paper the invigilator hands you, collected at the end. Anything you could not reasonably recall, a relative atomic mass for instance, is printed in the question itself.

Dates, registration and fee

Four macro-periods run between November and October, with eleven test days in total. You may sit the test once per macro-period, which means up to four attempts in a cycle. The fee is €55, paid when you book, and registration is made through the CISIA portal. Places on any given test day are limited and close well before the day itself, so the practical constraint is usually availability rather than the calendar.

A result is valid at every participating university for the cycle running from 1 November to 31 October. What it cannot do is outrun a university’s own deadline: normalised scores are published only after a macro-period closes, so sitting the test in the last window of a period can leave the score arriving too late to register.

Are there past papers?

No. CISIA does not release them, and since the test only began in November 2025 there is no back catalogue. The closest material is the English TOLC-I, TOLC-E and TOLC-F practice tests, because CEnT-S replaced those three exams and draws on the same syllabus areas. Anything sold as a CEnT-S past paper is either TOLC material relabelled or written by someone else, which is worth knowing before you pay for it.
