Would you please rate these tests.

Hi guys,
Since you are more experienced than me and you know about different tests and their quality, would you please help me to choose one of these tests My target is getting a score higher than 700.

A)For verbal:
I`ve studied all Manhatan books 3 times as well as Bible CR and I did all 700-800 questions from a pdf file which I downloaded from this website. Now since there are a lot of questions from different sources, would you please rate these tests and recommend me which one is more preferred?

B)For Math
I`ve studied all Manhatan books 5 times and I also have just finished GMAT Math Bible book and did all of its practice tests. And now since every source has lots of practice questions, I`m not sure which one is really worth it to be studied.
