What does it take to succeed in this dive?
This dive is 100% a memorization drill.  
That doesn’t mean it’s easy, nor does it mean it’s hard.  It simply means that with discipline, you will do well.  Without discipline, you will never succeed in even reaching Level 1.

The great news is that here in this handbook you will find everything you need to get started with, and master, this dive.
