Summer School - Transcript Questions

Hi,

I’m a junior in a public high school, and I’m thinking of taking an AP Calculus AB course over the summer at a fully accredited, private school.

I met with my counselor today who said that the result of the course wouldn’t be on my high school transcript. I understand that when I apply for colleges, I would then have 2 transcripts to supply.

Since the summer course won’t appear on my transcript, I’m assuming it won’t appear in my high school GPA.

My question is how (and can I) factor this in to my GPA and UCGPA when I apply to colleges?

Thanks!
