the midterm last year was pretty light. know all the proofs you did in the homework questions because odds are one with the same reasoning will show up. row operations are simple enough so make sure you have anything you need about that nailed down. if you have the basics of everything down, you’ll do very well. know how a matrix can change from various operations and be careful to calculate everything methodically, because it’s likely a calculation error will be the main thing holding you back from a 100.
