- talking and reviewing with one other person force you to THINK, and
- you stay organized a little bit better when you have someone to "synch" with regularly.
So go to the Discussion area, Study groups - find someone in your geographical area, type in a message with your geographic area in the Subject box, and see if you can make a new friend to study with.
From my previous semesters in PSC1121, it really helps a LOT.
As an example, I typed in a discussion posting for a study group on my home planet. :)
