Do I have to combine these GPAs?

The CSU app requires you to put in ALL TRANSFERABLE UNDERGRAD COLLEGE WORK GPA.

I attended a CC, took a psych class, got an A.
I then attended a different CC, took the same psych class (B Grade) and a sociology class (C grade).
They are the only two classes I took at CC #2.
I’m now back at CC #1 and retook the sociology class.
The B and C grade I earned at CC #2 give me a 2.5 there.
Question!
Do I need to calculate this into my overall transferable GPA??

Thanks in advance!

Yes.

Thank you!
