Hello guys! I have been taking a bunch of practice test from different companies ETS ppp, Manhattan, and Kaplan. I notice that the grading of Manhattan is based on the difficulty of the question, even if I have 15 questions out of the 40 in quant I can ended up with 158 if most of those questions are difficult or hard level. Now I have read that the GRE also grades the same way, but my experiences with the PPP 1 and 2 is completely different, ETS and Kaplan are only giving me a single point for any questions regardless of the difficulty level. Will the Actual GRE will be that same as the PPP grading or is more like the Manhattan grading based on the difficulty of the question?
PPP1: 304
PPP2: 301
Manhattan 2: 307
Manhattan 3: 310
Kaplan 4: 302
