What is the best way of revising for the exams?

Unlike some areas of academia, CREST exams are usually vocational; they are not designed to be achievable by a candidate whose sole focus is passing them through isolated study. They are designed to measure an individual’s capability to operate within the industry and identify those who can demonstrate the skills required.

The majority of successful candidates have gained real-world experience, augmented by training courses in certain disciplines, before attempting the examination.
