Exam prep brush-ups

Exam preparation courses are the regulatory required classroom training hours for each subject that are needed before taking the exam. At Cat3C we offer significantly more than the regulatory minimums. They are primarily aimed at our own ATO students although subject to availability we do accept external students.

Please note that if you are registered with another ATO you must attend your minimum classroom hours with them. Anything you choose to do with us is in addition to their requirements. We cannot authorise students from other ATOs to take exams based on attending one of our brush-ups.

Brush-ups at Cat3C

What is a brush-up?

Do I need a brush-up?

Brush-ups are intended to address any last-minute problem areas, particularly tricky areas and exam technique. You are expected to be broadly conversant with the subject. They are NOT intended as introductory courses, or super crammed full courses, but rather the final tune-up before the exam. Our own students must have already passed all their progress tests before attending the course. External customers are expected to be at a similar level.

Our own students are expected to do the subjects grouped by module.

Brush-up schedule 2021

Whilst we always endeavour to adhere to the dates below, it may occasionally be necessary to make amendments for operational necessity.

For external students, brush-ups are priced at £150 per day. For all CAT-100 and CAT-20 students, these brush-ups are included within your course fee. CAT-00 can purchase brush-ups at 50% discount.

CAT I, II, III schedule breakdown

These brush-ups are gradually being withdrawn as 2019 students work though the system. Where necessary, students will also be accommodated for individual subjects by attending new format brush-ups. There will be no further old format brush-ups after the end of 2021, although any remaining students on these courses will be catered for with individual training plans.
