⚡ Shortcut Tricks for Data Sufficiency
🔹 Trick #1: Don’t Solve Completely
Your task is to judge sufficiency, not to solve fully. Save time!
🔹 Trick #2: Analyze Independently First
Always evaluate each statement separately before combining.
🔹 Trick #3: Eliminate Using Options
Use elimination on answer options based on sufficiency logic.
🔹 Trick #4: Use Number Line for Comparisons
For questions involving numbers, use real values to test both positive/negative or even/odd cases.
