Hey, in a sense that is not 100% correct. In my case, I have actually performed better in advanced questions than in basic ones. I have wondered myself how is this possible. Then I realized that even though you know that you will be tested mostly on some i.e. parallelism questions, that does not automatically mean that there will be no idioms, modifiers, tenses etc. Thus, you can understand parallelism well but could do poorly on most of those questions because of other reason than not understanding parallelism. I would recommend you to make an
error log, and put down in a word document every problem that you did not solve correctly.
As I said in my example I had better percentage of correct answers in advanced questions than basics questions. I think the reason is that my knowledge has accumulated. For SC, you will need to know every chapter if you want to do well because GMAC, in my opinion, is mixing chapters when it makes those questions. So if I were you, I would do OG problems as soon I get a reference from
MGMAT guide.[/quote]
Ok thanks I will try this approach.
