GRE Math Strategies

Subjects : gre, math
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

12. Any arc length is less than






13. Any integer is divisible by 5 if






14. 1. square all choices given 2. select the closes choice that is too large and the one that is too small. 3. find the average of the two choices (not of the squares) 4. square the average - if it is greater than the original number - choose the lower
