Dropping gear is deciding what/when and more importantly WHY you are removing certain gear from yourself and/or the victim. For example, you might want to remove the weight belt to establish bouyancy in some situations...but not in others. Stuff you discuss in class. The most important thing is to stop and think about what you are doing and why. Again, stuff you discuss in class.
This doesnt have to be in a traditional classroom setting. A lot of these concepts can be (and should be) included as part of a briefing and debriefing while working on the actual skills? A lot of additional information and theory can be imparted by an instructor without necessarily sitting in a classroom.
Good, realistic scenarios, ample in-water time and detailed briefings/debriefings which evaluate the techniques used and discuss alternatives/options make for a far more effective method of training than sitting in a classroom discussing in a vacuum. CPR/O2/AED stuff can also be done on-site - which would probably be a more realistic approach than doing it in a classroom.
The fact is that the OP's question does not provide any indication as to whether or not the class is going to be enough or not. 2 days is a bit hectic, but depending on class size, schedule, etc., it could be doable as well. I would assume that CPR/First aid training would be done beforehand. I'd prefer to take 3 days - 1 day to go over theory, as well as the mental aspect of rescuing, but the main thing is the quality of the in-water training: 2 full days could do a very good job in this area.
I am always amazing by the detailed inferences that we here on SB can draw from such miniscule facts. Sherlock Holmes would have been proud.
The one minor nit I have with rescue training in a quarry is: no waves or currents, so potentially too easy. I just finished a rescue class 3 days ago in a monsoon sea (and yes, it was 2 days in the water - me & 1 student, with a couple of our staffers playing victims), and it was *wild* - but the student left knowing he could pull off a rescue anywhere after this.
