How to study?

1. Go back through every focus lesson and homework.  Review the problems you understood how to do.  Make a point to remember the steps you followed and why you got them correct.  Look at the problems you at one point could not work out.  Try again to see if you can figure them out.  If not what parts do you still not understand.  Make sure those questions are answered before you take your test
2. Go back through all of your notes.  Re read and if needed re write important points that you have a hard time understanding or remembering.  Try to do this twice a day to keep the information fresh in your head
3. Work through the practice test problems in the book.  Try problems you believe you remember how to do and work through problems you have trouble with.  Keep practicing problems till you feel comfortable.
4. Repeat steps 1-3 for at least three days prior to the test.  Night before the test, quickly review everything one more time and get a good nights rest.
