Nobody likes to cram. Try this tidbit to help you retain info.
After class, during study hall, or in the evening, go over your class notes for the day. Make sure you can read your writing. Make sure you haven't missed any key concepts. If you think you have, text, email or call your classmate the same day. Once you have all the info, read your notes and highlight the key items. This will help you retain information, as well as organizing your notes, and give you a head start in test prep.
