GMAT CLUB TESTS

GMAT is adaptive, and if one performs well early in the test sections, the subsequent questions get harder and harder. As 500 and 600 level questions are relatively easy, practicing 700 level questions is the ultimate key to scoring high.
GMAT CLUB TESTS were not only a BRILLIANT source of extremely hard 700 level questions, they were available in the form of actual exam style CATs. I haven't come across such a high quality practice tool anywhere else on the internet.
The QUANT section on the club tests has improved my knowledge base, time management and approach to tackling tough questions. I really have never felt this confident with the GMAT ever before and I am really grateful for this tool to have been available.
In short, don't think twice, purchase the GMATCLUB TESTS and get going!!
