I can easily get every question out of the sub 600 list but honestly have no clue how to even approach the 700+ list. Are there questions that fall inbetween?

Check our Questions Bank, where you can find 600700 level questions. Also, visit our Search Page to filter questions by various categories. Hope it helps. thanks a lot Brunuel. One more question. If i'm aiming for 80th percentile in Quant would i have to get a lot of these questions in your 700 bucket above correct? Want to know if i'm really far away from my target or just getting intimidated by 750+ level questions. Thanks again.

700+ questions a different ball game all together. The more I practice the more it dawns on me that you have to get these 700+ consistently correct to be able to cross the 44 mark in quant.
A long way to go... but thanks for the compilation Bunuel!
