Gmat club quant tests are must to get Q50/51

I am from engineering background, reaching 48-49 was easy after that pushing to 50/51 was hard. GMAT tests concepts that are basic but one should be very strong in basics and to get that thinking process during exam in 2 minutes is hard. That's when Gmatclub tests helped me to push me think in the right direction and the explanation to the questions by Bunnel is really great. I took around 15 tests each day one test, this helped me get used to the stress. If you could get consistenet 47-51 in gmat club tests you can get Q50/51 in GMAT test. Most of the questions are 700 level and the questions really test your basics. I took manhattan tests as well but Quant tests in manhattan are hard and lengthy but I dont think GMAT tests that kind of questions(my personal experience). The thing that helped is you can bookmark the tricky questions you came across and view the solutions before the real GMAT and this hlped alot. Last advice is even though you got the answer right see the explanations by Bunnel they are really amazing and will help you solve 700+ level questions in less than 1.5 min.
