Unless you’ve got an unusually gifted memory, just listening to lectures is not enough. Just reading Powerpoint slides is not enough.
You need to take notes in order to :
- Help yourself concentrate
- Have information to study later, using techniques that let you say and do things to help yourself.
Even if your instructor gives you notes, it helps to still write down examples, quick drawings, points that were stressed, etc.-some of these can help you remember information later.
