I have been reading all of the comment some negative, some positive others even encouraging I can't even begin to comprehend what you're going through . My advise to you is to not be discourage believe in yourself and never give up. I have faith that if you take a refresher class and also find your weakness and work on it you will succeed. As for me I am doing review for my board I am using Saunders and there is a test taking strategies book I borrowed at the library very good . Try not to use more than two ressources so you don't feel overwhelmed. Good luck God Bless
