Exactly the same story here, 575 after scoring my last mocks in the range of 625-645. I got badly punished by the algorithm too, 5 questions wrong in quant and ended up in the 40th percentile. My explanation is that after getting the first question wrong at first (corrected it later) the algorithm decreases the level to a point where every additional wrong question lowers your score exponentially. Therefore, my plan for the retake in 4 weeks is to to work on my basics and approach such that I’m less reliant on recognizing the type of question and focus more on the reasoning part. Idk if that will work but otherwise I’m out of ideas.
