Read And Review—Early and Often 

According to the Ebbinghaus Forgetting Curve principle, we forget 70% of what we have learned within 24 hours. Going over new ideas a day after class will help increase retention and comprehension—so make time each evening for a quick review. Break chapters into sections and review the material at the end of each before moving on. Make notes by summarizing the critical aspects of the reading so you can easily review them without having to reread entire chapters. Bookmark difficult sections to revisit later.
