I notice that my writing skills goes up after an English class. So the classes does help with skills, does anyone knows what does the rest of the classes do?
Arts definate related to artistic skill and photography?
Math should be intellectual since the skill book for intellectual is call "Mathematics: Understand, Retention and Application"
Business might be intellectual too, the skill book "Business Management for Ding-Dongs" is for uping intellect
Science is probably for gardening since there is a green house.
The rest are harder to guess, like history and psychology (charisma?), computer science (video gaming???)
I hope only studying skill is required to do well in classes and getting a good GPA and other skills less related.
