paid exams-free exams/recommendations?

I failed the exam last week and it was suggested by the admin that i take practice tests, free, and a couple of paid exams. could anyone recommend tests that they feel are good tests to take. i scored, 1 proficient, 1 mod proficient, and 4 below proficient. I used the PMBOK4 and andy crowe scoring in the 90% on his exams, but they were too easy compared to exam. Any help will be most appreciated in advance. Ray

Paid exams for PMP exam preparation I would like to recommend PMstudy (4 exams) and Rita's PM fast track.
