Just review the skills required in the dive log, course materials, or video's.
Our class did them all, some a couple of times.
I was impressed with the instructors, for both the check out dives, and in the pool (Different guys). With the number of students in the checkout dives (nine) the instructor was in constant motion. Regardless, he spent the time with each student to get each skill done. High fives and encouragement all around after each skill, so very positive.
The only time the instructor said he was worried was when on student went to switch to alternate air, and put the snorkel in his mounth. I guess this has happened to him before, and he says the end result is generally the student taking a big gulp of water, and then going into panic mode, often surfacing. In this case the student kept his head, and just put the reg back into his mouth.
The instructor indicated that mask clearing was one of the biggest fail activities for OW. That surprised me.
We were gearing up next to a NAUI OW cert class from CU, and I was *AMAZED* at their loose instruction. For compass navagation, the instructor was passing out compasses, and then asked the question, who has used a compass before? He then proceeded to outline the skill they were about to be tested on. I was amazed as they *OBVIOUSLY* had done none of this in pool, and apparently had not even discussed this in the classroom, or covered it in the text.
