CFAI Sample exams??? 2010, additional, recommend, should

kamara5

I have done three exams so far.
Schweser Book 1, Exam 1, AM: 75%
Scweser Book 2, Exam 2, PM: 74%
CFAI 2009 Mock Exam PM: 83%
I plan to take an additional four or five exams (3 hours each)..
Two of these will be the 2010 CFAI mock. For the rest I am wondering if I should buy the CFAI sample exams and take them, or just do the Schweser exams (book 1 or book 2).
Those that have done the Schweser exams and the CFAI samples, could you recommend which would be best at this stage?
Option 1: Do Schweser book1
Option 2: Do Schweser book 2 as it is harder
Option 3: Do CFAI samples and Schweser exams
Thanks!
