Hi, I gave PP2 yesterday and my first quant section was of medium difficulty (as corroborated from the PP2 walkthrough videos here), however, my second section was not of easy difficulty and I can only find solutions of the easy set on gregmat. I score a 17/20 in the Medium Section but an 11/20 in the last quant section, I wanted to understand the questions better- are there any walkthrough videos available that I can go through? I also scored 157 overall in quant which is much lower than what I’ve been scoring, but I was also very tired while giving this so I’m cutting myself some slack. But regardless, I didn’t know that scoring an 11 in a hard quant section implies a score below 160, despite the first section going fairly well?
