The Final exam is largely based on the unit quiz questions that you encountered throughout the course. The biggest difference is when you get to the Open Answer exam and have to write definitions and do a few calculations on your own. The final exam has a higher first-attempt passing rate than the Midterm, FYI.
So the best way to study is to review each unit and quiz, to refresh your memory. If you’ve been keeping a notebook, that will help a lot.
Keep a calculator, pen, and paper handy.
