Process of Elimination on the GRE

Verbal:

Extreme words ("always," "never," "all") are usually wrong in reading comp.

Answers that introduce topics not in the passage are wrong.

If an answer is half right and half wrong, it's wrong.

Quant:

On Quantitative Comparison, test edge cases: 0, 1, -1, fractions, large numbers.

If the answer works for positive but not negative numbers, it's D.

Data Interpretation:

Estimate first. If choice A says 45% and choice B says 12%, and your rough math says "around 40-something percent," pick A without computing exactly.

General:

No penalty for guessing. NEVER leave a question blank.

If stuck, eliminate what you can and guess from the remainder.

Mark and move on after 2 minutes. Come back with remaining time.
