I agree with the last post. I don't know the individual mentioned in the last post, but I would try and find a review/ cram course somewhere.
The real benefit to the class, in my opinion, is not so much the instruction (although that is great). It is getting away from family, friends, kids, hobbies, home projects, TV, office, etc. etc. for a few days to focus on nothing but passing the enrollment exams.
The after class discussions around a glass of beer with the other students is usually very benficial as well - you compare knowledge, actual working techniques, networking opportunites, etc.
It is a safe bet that more than one actuary has been known to find a job through networking with old classmates.
It has been about 15 years since I sat for the exams, but I am relatively sure that the pass rates are such that the majority of candidates fail each sitting. Anything you can do to "up your odds" is extremely well worth it!
Look, it may cost you $1,500 to attend a seminar (i.e. airfare, meals, room, etc.) However, if it saves you a year or two of sudying (because you avoid retaking the exam a couple times) it is worth every penny!!
Good Luck !
