Stratergy to upscale Q164-Q166 to Q170

Hi ,

I have a quants background and I sailed through GRE without studying any concepts but I did practice a lot of questions and mocks. Still stuck at Q164 to Q166, how do I go about reaching Q170

Get the strategies correct! It’ll save you a lot of time

And how do I correct those?

i did notice in my diagonistic , got many QC wrongs.
