I wouldn't be forking out $375 for a course. That does seem a bit over the top.
Have a crack at studying yourself and then do some 1 on 1 time with an instructor to go over the bits you're having trouble with. If the school charges $40 p/h for briefing time you'll end up ahead as $375 would give 9 1/2 hours of individual tuition. I don't think you'll need that much to nut out the BAK- it isn't that hard.
