Want to score more than 700

If you want to improve your quants score to 90% , try at-least 70% of gmat club questions and tests.
Lot of good and tough questions in single place .

Pros:
Good selections of quant questions
detailed answer explanations
enable you to find new shortcuts
Improve your timings

Cons:
Not adaptive like GMAT
Scoring methodology can be improved
if you tried other tests by different clubs (e-gmat, manhattan), you may see some repetitive questions.

My recommendation is take detailed notes for all the wrong answers , review the answer explanation , find new shortcuts . This feedback loop process will improve your score .
Finally time all the tests , it will help you find new way to solve the complex quant questions.

But overall wonderful resource to improve your GMAT score.
