also, how can i fit wharton courses into my schedule?
I don’t think you can use non-college courses to satisfy gen-ed requirements but to completely sure. However, you could use your free electives to take wharton classes. Also in general most college majors require around 32 credits to graduate which is 4 classes per semester. You can always take a fifth class during one or more semester or take a summer class to fit in more wharton classes.
Take a look at this. It might help.
