Once again, I may be stating the obvious, but I will say it anyway.
If you forget what you have learned as you progress through GRE Quant, then you will not be able to answer questions quickly on test day.
So to ensure that too much material is not forgotten, revisit your notes or flashcards on previous topics often. Work on mixed-topic problem sets as well.
For example, consider a scenario in which it has been over a month since you completed linear and quadratic equations and exponents. It would be a good idea to complete a mixed problem set covering those topics to ensure that concepts have not fallen through the cracks. Using the data from that problem set, you can easily identify the areas that need work before you move on.
You will rinse and repeat this process for other topics as you move through your study plan. By engaging in all of this review, you can ensure that all GRE Quant topics remain in the forefront of your mind, allowing you to answer questions with speed and precision.
