You could read throught the notes you have taken in class, and refer to the teext for extra bits of information. Cornell notes can be helpful as well.
I suggest you go on to google, and type in : cornell note taking method
After typing that in, click on the second site.
You could also go on to google again, and this time type in:
best method to study
There are a lot of good sites on the first page, which give you good recommendations on how you should study.
These sites might be handy.
Although all of these suggestions may not apply to you, most of them should be helpful.
Probably a little late.. 6 years late. Sorry. I'd suggest sitting down in a quiet well lit room with no distractions, lock the door, remove your electronics and try not to fall asleep. (Posting because kids in this year might see this, or future years)
