GPA question

I wonder then, how an arts high school figures in to the GPA calculation and so forth. I know they may only go by core classes like math , English etc but my D has half of her day devoted to her arts classes which is not really typical of a regular high school… I would think some colleges that she is applying to for theatre as her major would look at those arts classes in a different context because of the major and the arts high school being her high school… I guess that is where the school profile comes into play. Her school has 300 kids so they don’t actually offer as many classes of AP that a typical school does.

Plus someone mentioned going from an AP Lang class in junior year to an Honors English 12 class was negative… My D is doing this but simply because AP lit was the other English AP & she wasn’t that interested in it. She is doing great in AP Lang and is taking AP US history senior yr so it’s not cause she’s trying to be a slacker lol it’s just interest reasons , plus again, not loading up on AP classes senior year since she’ll be auditioning etc.
