Study guides

In short

Practical plans to study dive theory: a two-week plan for the Open Water exam, a six-week plan for the divemaster theory exam, every formula on one page with worked examples, and a quiz night to review with your dive club.

The exam date is set and the manual is on your nightstand. These guides turn it into a daily routine: what to learn first, how to test yourself, and what to do the night before.

Your next certification starts on dry land.

62 short lessons, 372 explained questions and a practice exam for each level, from Open Water to Divemaster.
