What to study with

One short guide per subject: the free official material first, then the one book worth paying for, then free practice.

Kestrel Exams makes free practice tests and study guides at kestrelexams.com. Students keep asking what else to study with, so this site answers that question subject by subject.

How we choose. Free and official sources come first, because the exam body's own documents decide what is on the test. We then name at most one book per subject, the right edition for the current exam, and say who it suits. Book links are affiliate links and every one is labelled where it appears.

For graduate students and researchers

If you hold or are working towards a master's or PhD, or you are a post-doc or an advanced researcher, Handshake AI's MOVE fellowship pays subject experts to check the work of AI models. It is not aimed at exam candidates, and the pay terms are Handshake's, not ours. We don't vet or guarantee the work.
