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.

I would not worry too much about Princeton. Their questions are less known and likely less debugged. There is also no certainty about the algorithm. I would go off more reliable scores.

PS. While they have updated their courses recently, still not many people take the their tests/CATs.

It's hard to say. None of us knows the exact algorithm that the GMAT uses to determine your score and give you questions of a certain difficulty, although we do know the basic outline of how it works. It's definitely true that missing many questions in a row is bad for your score, and missing many questions in a row at the end can be particularly bad, since you don't have any time to 'recover' from the resulting decrease in your score. Unfortunately, your score isn't just determined using the number of questions you missed and the difficulty of those questions (and assigning questions one specific 'difficulty' at all is pretty pointless, see this article for details: https://www.manhattanprep.com/gmat/blog ... -question/). It turns out to be fairly complex and difficult to predict - plus, we don't know what assumptions Princeton Review made when they designed their own algorithm, and whether those assumptions were correct.

Long story short - I wouldn't worry a whole lot about the relationship between your score and how many problems you missed / how hard those problems were. Not on GMATPrep tests, and definitely not on 3rd party tests.
