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.

14. Any integer is divisible by 9 - if






15. If an equation can be put into the form y= mx +b - then






16. C²= a²+b² and angle x and y are equal to 90°






17. 1/an






18. y years from now

23. What % of m is n






24. (amount of increase/original amount) x 100






25. B>c+ d>e






26. M?A = m?D m?B= m?E m?C=m?F and a/d=b/e=c/f
