I finished TTP and I had a high accuracy 60-90% on all hard chapter tests. I also finished the OG questions and had around a 15% error rate on the hard questions. I took two official practice tests, and scored 82 and 84 in the quant sections. I had a lot of extra time left for quant in one of the tests.
Now I'm doing the GMATCLUB practice tests and I am getting destroyed. At this point, I don't even treat them like tests because I only make it through 1/2 to 2/3 of the questions before I run out of time. I just treat it like untimed practice questions at this point.
Getting really nervous because my exam is in 4 weeks. Are GMATClub questions really that much harder or am I just getting dumber? I never struggle with the actual concepts. It's more with thinking critically and finding an intuitive way to solve the problem.
Any help or advice is appreciated.
