Quickest Way to a Q51

Having gone through OG and Manhattan materials, I can safely say that the quickest way to gain that coveted Q51 score is through GMATClub tests. I scored Q47 on my first try using the aforementioned materials, and was looking for that extra boost to get the Q49+ range. The tests are punishing in their difficulty, but also elegant in a way that truly test and hone your concepts. I would recommend doing these tests untimed first to gain a sense of the difficulty of the questions, and then timed to really build your test-taking skills. I ended up scoring Q50 my second time around on the GMAT, and these tests played a huge role in allowing me to do so.
