Which strategy for understanding and remembering information is Isaiah practicing?

This question is missing the options. I've found the complete question online. It is the following:

Which strategy for understanding and remembering information is Isaiah practicing?

A. understanding the big picture

B. getting organized

C. staying up all night cramming for the test

D. overlearning the material

The strategy Isaiah is using is:

C. overlearning the material.

Explanation:

When we overlearn, we repeatedly practice a skill at a certain level. It means we do not change the level of difficulty, but simply practice the same things over and over again. That is what Isaiah is doing. He's using flashcards and recordings, he's asking friends to quiz him, but all the while he is studying the same things - the vocabulary he will need for his test.
