Series 6 and 63. These are not bad at all, I have them myself. Study the literature and take as many practice exams as you can. Try to take 3 exams per day. Most of the info you will not remember - this is a cram type exam. So study then take and exam, study then take an exam, study, take the exam. You don't need to understand everything but you will need to know the answers. Multi choice too...good luck.
