GRE Math Practice Questions: An Important Takeaway

How did your mini-GRE math practice test go? If you missed some (or even all) of the GRE math sample questions, don’t despair! You can still get the GRE score you want—and get into the graduate schools of your choice, with one big caveat…

When practicing GRE math problems, the key is to figure out why you answered questions incorrectly. Are you having trouble with the Numeric Entry question type? Are questions about geometry giving you the most issues?  For a lot of students, it’s Quantitative Comparisons that prove tricky.

At first, this process can be frustrating. But, remember, by forcing yourself to figure out the answer instead of immediately turning to an explanation during your GRE math practice, you will understand the problem at a deeper level and be less likely to miss a similar problem in the future. GRE math practice questions can help you get there.

This process of practicing and reviewing is the best (and really the only) way to improve your score on the GRE. With enough GRE quantitative practice, you’ll get the score you want! And for more good habits that’ll help you get that high score, check out this video:
