CSEC maths practice, marked the way an examiner marks.

Live and free, with a sample student that opens without an account.

ExactMark on a computer, for a sample student called Keisha: today's session of about twenty minutes (reviews that are due, a new topic, then mixed exam practice), a grade estimate of IV with the two topics that would raise it fastest, and her readiness for each of the three 2027 modules. — A sample student's plan for the day on a computer, and a factorising answer marked for its form on a phone.

ExactMark on a phone: the question asks to factorise mn − 4m + 7n − 28 completely. The answer m(n − 4) + 7(n − 4) is marked 2 of 3, because it is equal but not yet factorised, with a prompt to write it as a product of brackets. — A sample student's plan for the day on a computer, and a factorising answer marked for its form on a phone.

ExactMark is free practice for the 2027 CSEC Mathematics examinations. A short level check finds where a student stands. After that, a daily session of about twenty minutes teaches the next topic and brings back anything due for review, and timed papers follow both 2027 formats. Every answer is marked for its value and its form, and any mark held back comes with the reason.

Kinds of work: Custom software, Assistants

Students type their answers on a phone the way they would write them, such as 2½, x² or 3(x + 1). An answer that is equal but not factorised, or correct to the wrong number of decimal places, earns part of the marks, with a note of what is missing.
Every question is written for ExactMark and made fresh each time, so practice never runs out and no past paper is copied. Before release, each kind of question is generated hundreds of times and checked against its answer, and against the wrong answers that common mistakes produce.
Progress stays on the student's phone, with nothing to sign up for. Once opened, it works without the internet, reads questions aloud, and makes a weekly report that a parent can open from a link.
