In my experience, it really wasn't an "advanced subject" for me. Sure, the majority of majors who are trying to become doctors, CS, or computer engineers only have to take up to calc 2 (and diff eq) for their bachelors, but I still wouldn't say MVC or diff eq is an advanced math subject. Real analysis or algebra -- where you have to take a math course on mathematical proofs before taking these classes -- is where I'll say math becomes more abstract on its applications and advanced.

Diff eq was not challenging at all, I spent probably 6 hours a week on average (which includes the 4 hours of lecture). Its as simple as solving a linear equations, with it being slightly more tedious. If you understand derivatives, integrals, and partial fraction decomp (for Laplace transforms) its a breeze of a class.

MVC on the other hand was slightly more challenging, but having finished calculus 2, that too was also very enjoyable.

Point is, MVC and diff eq aren't hard classes I wouldn't even call them advanced classes as that title goes to analysis.
