Hi,
I had very similar problems. This article by Stacey was very useful to pinpoint where I was going wrong:
http://www.manhattangmat.com/articles/a ... estion.cfmMy mistakes were:
-Not classifying the question by its wording
-Inferring too much - school day habits. On the GMAT, RC inference questions are very similar to CR inference questions. You cannot infer something that cannot be directly supported by the passage.
-Specific Detail - not going back to the passage to check what is explicitly stated in the passage.
-Stuck between two answer choices - the key here is to eliminate answers that are incorrect because of just one word in them
Working on these via OG and verbal supplement has improved it for me, but I still get the odd one wrong. This is a process change and requires a lot of discipline.
But the above are specific to me. As the article suggests, it will be different for everyone
Regards
Sunil
