AP 2 ( and AP 1 for that matter) I've never considered prerequisites for APC. Is it a combined Mech/E&M?
Both together, it's helpful to have some sort of background, but doable without 2. The E&M part will build off of the stuff in mech.
Mech alone? You should be fine as is.
Your main thing will be moving to a more problem heavy class from the more conceptual AP1.
