GMAT Club Tests are THE Best - Quant Section replicates the Real GMAT Experience

GMAT Clubs Tests offer very Real GMAT like experience. I strongly recommend the test series to all test takers. The test series is, by far, the best test series available.

Quant Section
The Quant Sectional tests contain questions very similar to those appearing in the Official test. The in depth forum discussion of problems and the corresponding solutions adds a lot of value while preparing for the test. Practicing very difficult problems is of very little value - something that most test takers do and eventually get demotivated during Test Prep. GMAT is all about practicing as many GMAT like questions as possible - ONLY GMAT Club Tests come near the Official Guide in this aspect. The analysis of problems in the forum is simply invaluable. GMAT Club Tests are a MUST HAVE for all test takers aiming for a Q50/51.
Additionally, these tests help you to build endurance required for the Quant section. I have noticed that after taking several tests, I can now finish the Quant section in 65 to 70 min.
If you're aiming for a Q50/51, you simply cannot afford to miss these tests.

Verbal Section
Contrary to several reviewers, I do not believe that Verbal section is any less effective than the Quant Section. We must realize that, unlike the Quant Section, Verbal Section encompasses several topics - Sentence Correction alone demands learning obscure Grammar rules. I strongly believe that Verbal tests are equally good. However, I have some reservation on the scoring algorithm of the verbal section. On GMATPrep tests, I can score 40+ with 8 to 10 incorrect mistakes; In GMAT Club tests, however, such number of incorrect responses warrants a score well below 40. But, I am happy with a slightly deflated score because it keeps me grounded and competitive. Please make sure you go through the forum discussions - you'll most definitely learn several new things. Books always do not teach you everything.
