I need 20 more CPEs before next month, and I'm looking over Category B, which I haven't submitted anything for over the last three years. A few weeks ago I got Open Water Diving certified through PADI, which involved 10-15 hours of online training and about another 20 hours of hands-on training in the water. Would this kind of thing count as category B, or is that too far out of scope? And given I haven't submitted any Category B items yet, can this all be done at once or am I limited to just 10 for this year?
