Should try

I redeemed my Gmatclub Point to get 6 CATs from Manhattan Prep GMAT. Thank you all for the reward.
Manhattan Prep GMAT CATs have many extremely hard questions, particularly in the quant section. It's a good experience for those who want to practice solving hard questions and prepare for facing psychological pressure in the test room.
I think Manhattan Prep GMAT CATs should improve the adaptive questions during the test. I saw from the report that when my estimated verbal score was 30, I was assigned to a series of 6 hard questions with the difficulty of 700-800. Unbelievable! I wonder if, in the real test, we will also face this problem.
