How are you using Electives?

I checked "All of that", but I mostly try to find a subject that kind of specifies the sim's interest in the chosen degree. For example the Economy student who I know will become a very greedy business person, might add Mischief to the mix as an Elective. Someone into culinary might add a Business subject because the sim might want to start a bakery later. Someone into Psychology might add something including Parenting because he will focus on psychology for the youngest life stages later on.

It probably makes no difference later on, but it feels more individual when I can mix the subjects a little.
