Hi, I'm an incoming freshman at Penn and I was thinking about taking the credit exam during NSO for Math 1070. For anyone that's taken Math 1070 or the credit exam, how should I prepare for it over the summer? Is there anything new that I should learn? I got a 5 in calc BC if that's relevant at all.

Also, is there any real benefit to taking the credit exam? As of now, I'm just taking it because I don't want to relearn stuff I probably already know (if I'm not mistaken).
