Very thorough, Great Value for Money

The Quant Section is very good. The questions are challenging, and the best part is you have multiple people giving and discussing each solution on the test - so if the official solution shows a different method of solving than what you used, you can always see different points of view and verify whether what you did was correct. The questions' discussion is a two way street. The Quant tests are REALLY good at helping you get a feel of the real test, and to get used to challenging questions. I dont think there's anything comparable at this price range on the internet. I think the best thing you can do is to give a test and recheck methods for each question before giving the next test. This way ur actually improving.

The verbal section is good; however, I wouldn't take the Verbal scores too seriously. Also, the official GMAT has 4 RC passages most of the time - each GMATClub Verbal test had only 3. This gives you a lopsided feel for time. Also, I think the grading is harsher in Verbal than the actual GMAT. Never crossed the V: 36 mark in the tests.

My actual GMAT score turned out to be:
Q: 47 (GMATClub scores' average had been 49)
V: 38 (GMATClub scores' average had been around 34)
Scaled Score: 690


You can't go wrong with GMATClub Tests.
