gmatclub test

I purchased gmatclub tests three months ago and am writing this review to renew my subscription
Verbal is not helpful and I don't recommend it to other people who are studying for gmat. They often have ambiguous answers that will just make you confused. I often could not agree with the answers especially in verbal.
Math is really challenging and helpful, my quant boosted from 37 to 47. I highly recommend gmatclub practice tests to anyone who is aiming for 700+ in gmat. I gained a ton of knowledge that helped in solving hard math problems. Practice mode is really good because you can see the solution one by one right after you solve each of the questions.
