I'm currently in the early stages of Jeff Sackmann's 10 Challenge Sets; 2/10 done. Will tackle the
GMAT Club tests afterward. I took 6 CATs prior to starting:
GMAT Club Free Quant test: Q44
MGMAT - Q43
Kaplan - Q47
Economist - Q49
GMAT Focus - 47-51 (Gmat focus gives a range) Also tells me 99.97% probability of "excellent" on DS and 84.05% probability of "excellent" on PS; whatever that means
Princeton Review - Q45
I understand my that "true quant-ability" is somewhere above Q40. However, Princeton Review left me baffled. Hear me out:
I correctly answered 19 out of the first 20 questions (only missed question #3) -- even as they got progressively difficult (Questions 9 to 19 had difficulty ratings of 8 or 9). For questions 21 to 31, I missed 7 of the 11 total questions, all of which had a difficulty rating of 9 or 10 (I believe 10 is the highest difficulty rating). The only missed question in the entire test that was not rated a 9 or 10 was question 3, which had a rating of 7. Anyone had a similar experience with Princeton Review? I understand that the only test accurate test prep out there is the GMAT Prep software, but wouldn't getting the first 19/20 questions right constitute a higher score? I plan to take the GMAT Prep software exam after Sackmann's sets.
Thanks in advance,
