Calc 2 will resolve the Calc 1 issue as math is a validation subject - meaning Calc 2 implies you know Calc 1, so even if you didn’t take it, it is assumed you know it. So if you get into Calc 2, you’re good to go.
You will get the units for the AP course regardless. It’s just that it doesn’t always fulfill the subject part. For instance, if you completed precalc and the dept says AP Calc needs to be a 4 to fulfill Calc 1, you won’t have fulfilled it with a 3. But if you take Calc 2 anywhere it validates Calc 1, so the issue is irrelevant.
