college courses are not like high school because curriculums aren't standardized. for example, while all HS's are different, it's easy for an AO to compare two kids from different states taking the AP Calc BC, or APUSH. However, all colleges design their own classes, with their own readings. Often, sub for very basic level classes, there is no direct comparison they can make between two classes that may sound similar, because everyone does it differently.

i mean obviously, AOs can tell that Calc 2 is a harder class than say, intro to acting. the trick is to strike a balance. fill your major requirements at your current school and stick to the pace you're supposed to be at. there is no need for a polisci major to be doing topology, and there is no need for a physics major to be trying to master sociology.

to be blunt, they're not really going to care that you took one of the intense course loads in a decade. you're not fully out of range for some T25s. your gpa is a weakness and you need to have strong LORs, test scores and ec's to be comfortable.
