I recently took a final for forces and I think I did okay, but I could have done better. I recalled terms like Newton's First Law and I graphed the variables well. I think I didn't do very well on my conclusion and reasoning because I didn't study it. I should have added the formula to calculate forces in my reasoning paragraph. I would probably do the same because I haven't learned anything and I didn't go over my notes after that test.
A semicolon wouldn't work because you aren't comparing, a comma wouldn't work cause you aren't listing or comparing, and a folon wouldn't work because you aren't listing. Also cause ni punctuation makes the most sense.
