VerbalHub is a good platform for those who are weak in GMAT verbal. If you are not able to get your desired score in GMAT Verbal, you should join it. Let me share my experience. I took one-on-one GMAT verbal coaching because it does not have any group session. although one-on-one GMAT verbal coaching is a little expensive, it is worthy. I got personal guidance and I got 41 in Verbal. Few things about VerbalHub that you will get here: topic wise question, section wise question, many mock tests, and their evaluation. I especially liked the 11 full-length tests for preparation. one negative thing about VeralHub is it does not reply to the message instantly rest of up to the mark.
