Hey guys,
Good questions, Gurpinder, and great answers, Nicole!
For Sentence Correction, I'll add to what Nicole said with a few thoughts:
1) SC is definitely a process-of-elimination exercise, so when you revisit problems make sure that you know why the wrong answers are wrong.
2) In doing so, see if you can give them one- or two-word "tags" with the kinds of errors that you know come up frequently (e.g. "Modifier" or "Subject-Verb Agreement"). This way, you're not looking at an array of individual errors, but rather some systematic categories that come up frequently, and training yourself to seek those out.
3) Don't let yourself get away with "Idiom" as a description nearly as much as the OG solutions do. Try to find a different category whenever possible...honestly, you should be able to do so well over 90% of the time. "Idiomatic" is the GMAT equivalent of Jeopardy's "Potpourri" category - it's a catch-all for a random assortment of errors. The GMAT is not a random test - its job is to ensure over 250+ days of testing per year all around the world that your score is relevant to that of someone else. It's a standardized test, so try to view your SC errors through that same ideology.
4) If you're really struggling with SC, try this - do a set of 20-25 questions and each time you eliminate an answer choice write down 2-3 words explaining why (e.g. Pronoun Agreement). Then when you return to the questions later, you have a quick-access "journal" of what you were thinking when you completed each question, and you're also training yourself to have reasons for elimination other than "it just sounds wrong".
