How's My Progress Coming Along (Need Critique With My Test Scores) Thanks in Advance!!!!

Hello fellow PMP and PMP aspirrants.  I have been studying for the PMP exam for the past 2.5 months and have been finall honing in on the target date (Feb 21, 2012).

This is my preparation book wise:

Rita 6th Ed (read twice, finishing up 3rd time as we speak)
Andy Crowe (read twice)
PMBOK (read three times - two times recently, one time a year ago)

Test scores
Rita PMP questions (about 60-70% when I started)
Andy Crowe (about 80%)
PMPerfect (all tests, averaging 75% total)
Tutorialspoint (61%, discouraging)
Oliver Leahm 175 Q (77%, very encouraging, considering its difficulty)
Headfirst (87%, very encouraging)
Simplilearn (67%, unsure of how to interpret this)
PMStudy1 (77% per the evaluation, but I only got 135 out of 200, so that would be 67 or so %)

Is this sufficient or will I need more studying?

I am planning on taking 3 more Simplilearn exams, the other 3 PMStudy exams, and the PMZilla hard questions (thinking about doing this in the next week so I can use this to reassess my knowledge with the final knowledges). 

I am just wondering if this will be sufficient, because I want to NAIL this exam.

Thanks for your help...
