Would've been nice to spend more time on EACH skill. However, I did not pay for the class and the person that did would have to get a refund from his own friend. It's a crappy situation to be in, so I'll suck it up. I plan to practice a lot more in my girlfriend's parents pool (heated) and with her brother afterwards (he's an instructor). Also, we have all our rental gear while they are sorting out dates so that's good (free of charge of course).
I would advise against practicing in the pool by yourself, hopefully you mean her instructor brother will be in the pool.
I agree with RJP, it's so easy for those of us that have ben diving awhile to take things for granted that new students don't even have a clue. New students are often naive and trusting, hesitant to make waves or challenge the instructor on anything.
And I've also seen shops that tell the prospective student whatever they want to hear to sell them on the OW class then spring the surprises later. They don't lie if asked but they don't volunteer stuff like how cold it will be or all the stuff you have to buy unless you think to ask.
