As helpful as a private tutor

GMAT club tests were recommended to me by a close friend.
I started my initial GMAT prep using OG 2021. Although I was satisfied with the verbal question back, quant questions were pretty average. I needed something they could challenge me & give me the real exam feel before the actual test. So I went for the GMAT club tests & started evaluating my performance on a regular basis. Believe me, the Quant questions in these tests are going to blow your mind. They challenge the way you approach the problem, your basics & provide you a stressful experience much harder than the real exam.
For verbal prep, I had other sources as I didn't find the GMAT club question Bank consistent enough.
Overall, GMAT club tests are absolutely amazing and I recommend every test taker to go for these.
