Series 7 Exam

Okay, I need help. I have to take the series7 exam in about two months. I have to pass this exam or I am deep doo doo. Any advice about studying. I have the passperfect books and I understand that they are the best out there. Are there any CD's I can listen to while I drive or prepare dinner or something. I spend an hour and a half atleast driving to and from work, I can use that time to listen to CDs that can help. I will appreciate any advice I can get on how to study and how much time you put in to study and pass. I only want to do this test once. I have two babies under two. I don't have time to be re studying crap.
