How much are AP classes going to boost my GPA?

So during my Freshman year, I did very poorly in all CP classes but I brought it back up during my Sophomore year. Now im taking 3 AP classes and 1 honors class, if I do very well in them how will it affect my poor GPA? It shows that my gpa is 88% currently.

You need to ask your guidance counselor. High schools calculate GPA differently.
