I can see that in a lot of those answers I am kind of jumping the gun and saying that they neither A nor B are not sufficient.
You're falling for traps. These were tricky for me too. In my opinion, the GMATClub tests
are the best DS preparation available. Those DS questions are frustrating and very tricky, but they (painfully) teach you what to look out for.
I gave a gmat prep test right now and have completed the math and to try and be better at DS i was giving it more time which ultimately resulted in me randomly clicking the last 5.
Just to clarify, but did you not
take the full exam in one sitting? As for timing, that will improve overtime. Just time yourself for each practice question. If you take longer than two minutes, mark it as incorrect (but finish it!).
As for the Verbal, I had 28Wrong out of the 140 in SC and 15 wrong out of 95 in CR. I am not going to spend too much time on the RC other than OG12
and verbal reviews and will do it once towards the end.
Is there a reason why you are placing less emphasis on RC? Hopefully, it's because you perform well on it. If not, be careful. It's important not to assume anything about the GMAT. Be active about your studies.
An 80 percent on SC is decent, but you can probably improve. Make sure to reread any SC guidebooks and fully review every SC explanation - even for the ones that you answer correctly. An 84 percent for CR is, again, decent. As for SC, review OG explanations and make sure to read a guidebook on CR if you haven't done so already. The main concern for this section is that the verbal questions found in the OG are easier than the ones that you will see on the test.
