SC Strageties from Manhattam GMAT

vhaditya memorizing things with a few exceptions (such as fundamental equations in Quant or some common idioms in SC) is a bad idea. Process of Elimination (POE) is by far the best strategy in SC. Before starting the POE, you should invest at least 50% of the time in reading the original sentence and making sure you understand its intended meaning. While reading the original sentence, you may simultaneously hunt for obvious errors such as SV disagreement, misplaced modifier, pronoun error, parallelism issues, comparison error, and so on. During POE you are essentially looking at each answer choice and try to find the issue with it. I am not nearly as good as Verbal experts such as generis and GMATNinja, but they will likely say that 80% of the SC questions (even hard ones) contain at least 2-3 answer choices that are quite obviously wrong.

My recommendation is to go through one resource, e.g. Manhattan SC guide, do all problems at the end of each chapter, and then start practicing SC questions from OG. You may want to be selective about the source of your questions. I suggest to use OG and maybe few more resources such as Manhattan & Veritas Prep. With enough practice you will likely be able to automatically say whether the question is official or from a 3rd party.

Good luck!
