Do summer classes count towards your college GPA when you are currently in HS?

Applying to College

I am currently a senior in HS that is planning to go to community college for a year and then transfer to USC as a sophomore. And I was wondering if I take summer classes in my community college after my HS graduation would they count in my GPA and transfer units?

Any college courses taken after High school including summer would be included in your Transferable College GPA and the units would transfer if USC accepts them.
