Question about UC GPA when your school only reports one grade

So my school only reports end of the year grades. Not trimester grades. Will my AP classes be counted twice for each semesters worth or only once because there is only one set of grades? This would make a big difference to my UC GPA and therefore my chances. Thank you

You enter your grades into the UC application exactly how they appear on your transcript. For the GPA calculation, you can double each grade and input into the calculator along with the extra honors points (up to 8 semesters) or you enter with 1 grade/year and just use (4 extra honors points for the year) and you get the same GPA. I tried it both ways and I get the same answer.
