A few of you have asked about supervisor prep, so it's now live. Air Diving Supervisor: 3 full 100-question papers (physics, physiology, working practices) Bell Diving Supervisor: 3 full papers (physics, physiology, chamber practices, bell operations) Both include 3 UK legislation modules (HASWA, DWR 1997, ACOP L103/L104, RIDDOR). Timed like the real thing: 2.5 hours a paper, a 75% pass mark and a pass needed in every section. Every answer is explained. One thing worth knowing: a supervisor pointed out that in the first version you could often spot the right answer because it was the longest. That's fixed. The answers have all been rewritten and shuffle each attempt, so these papers test what you know, not how well you guess. These are separate from your portal membership: £49.99 each, Air or Bell.
