GRE Logic / Critical Reasoning Passage Strategy
Strategy for logic passages (also known as critical reasoning passages) on the GRE is markedly different from that for normal reading comprehension questions.
The good news is the passage itself is typically really easy to read. The bad news? You'll have to think, not just find stuff in the passage like for normal reading comp. The answer choices will be NEW information that isn't in the passage at all, and based on the question, you'll have to use logical reasoning to determine if that new information satisfies what the question in asking.
In the below video, I demonstrate how I deal with a "weaken the argument" question.
