Thanks for the fast responses, everyone!! This is helpful. 
@mikemac Are you certain that my local community college wouldn’t be able to certify my IGETC courses b/c I am a high school student? I’m just scared that when the time comes that transferring the credits will not work out as well as I thought it would because you never know what might happen!! Of course I’ll be asking college advisors, but I want to have some sort of idea on what possible problems there are and how to ask it before I schedule calls and appointments.
