Hello, FreeSpirit! While I cannot provide an opinion for you on non-Official GMAT test prep products, I am happy to point out some products we produce to get you started. First, if you have not already done so, GMATPrep is a great first step. It is free and comes with practice questions, study tips and a practice exam:

You may also want to try the Official Guide for Verbal Review for practice questions and study tips:

I also recommend you re-post this question on one of the main message boards so other students can let you know what has worked for them. Good luck!
