How important is it for students to do well in pre-calculus before taking a first semester calculus course? It took pre-calculus in 1993 and got an A minus. Not bad for a person who did not major in math, right?
Yes, an A- in pre-Calculus is pretty good. The fact that it was 21 years ago, not so much!
If you are at all0 unsure, retake it. That's better than taking the Calculus course, failing it and then having to take both Pre-Calculus and Calculus.
