How should you study? Start NOW – re-do all quizzes & exams. Review your notes for sample
problems. Do an hour or two every day – don’t try to do all of your studying in a day or two!
As a reminder, you can put formulas on an 8 ½ x 11 sheet of paper for the final. Worked
problems or examples are not allowed and will result in not being able to use a formula sheet at
all.
