Anything that you wish you had known before committing to prep schools?

Thats right! I have seen their course catalog and they do have many courses. I have completed my Calculus so just trying to plan ahead. There are many kids at SOHS who do not take Math courses there though they are advanced university-level courses, because there is no college credit. No harm in knowing the options right? Especially if it is going to cost so much!
There is also the factor of getting admission, however, I would like to know what I am getting into and plan accordingly.
I agree that’s not the reason to take courses, just trying to understand if there is a way they can get college credits.
