Why practice

Practice is the best way
to learn

Research shows that practice is the most effective way to learn and retain knowledge, outperforming methods like highlighting, rereading, and summarization. In one comparison, practice led to 88% better retention after one week and 54% better knowledge transfer than rereading.

That's exactly why exabrain is built entirely around practice, so you can use it throughout the entire semester, during and after lectures, to learn anything as effectively as possible.
