Ugh, that's annoying. First, FYI, they did say they were going to take idioms out, and then they backtracked and said they were only taking out American-English-centric idioms. But they haven't told us which ones they consider American-centric. So... study idioms.
Next, I want you to go and analyze the problems that you missed on GMATPrep and then come back here and tell me WHY you missed them. Look at this article for how to do this analysis:http://www.manhattangmat.com/articles/a ... roblem.cfm
And here's an example of that type of analysis on a specific problem:http://www.manhattangmat.com/articles/GMATprep-SC.cfm
What was going on? Were there rules you simply didn't know? Did they get you to fall into traps? Did you make some careless mistakes? Etc.
Two big trends to keep in mind as you do this analysis:
- They have been increasingly emphasizing *meaning* in SC. Have you been studying meaning? Do you know how to tackle SC from that point of view?
- There have been an increasing number of "big parts of the sentence changing around" questions, often characterized by long underlines. How do you handle those? Do they cause you extra trouble?
For the first set, meaning, here are some resources (you can browse our blog over the past 6-8 months for more):http://www.manhattangmat.com/blog/index ... orrection/http://www.manhattangmat.com/blog/index ... on-part-2/http://www.manhattangmat.com/blog/index ... h-meaning/http://www.manhattangmat.com/blog/index ... problem-2/
