Can you suggest the best technique/hack to handle Data Sufficiency problems on GMAT?

Answer 1

There is a 5-step process. Step 1 is reading the question. Step 2 is determining what we know and don't know. Step 3 is evaluating statement 1. Step 4 is evaluating statement 2. Step 5 is evaluating both statements. I cover the evaluations in more detail with my direct students.

Good luck!
