VERY HELPFUL FOR QUANT!

GMAT Club Tests are great in case one wants to practice higher-level quant. In such tests, one can typically expect to see close to twelve 700-level questions, ten 600-level questions and the remaining 500-level questions (for a late 40s level). The questions tested are not lengthy but tricky, a kind similar to the ones that a student can encounter in the actual GMAT. The concepts tested are also very much similar to the actual test. Verbal tests are decent for practice too, however answers to few questions can be debatable at times. In case of verbal, it is best to rely on official sources.

Disclaimer: Given that the test is adaptive, the proportion of questions across varying levels of difficulty may vary.
