Some colleges* prefer or require at least a year of high school art (or semester of college art) for frosh admission, so she may want to keep ceramics to avoid problems with some colleges if this will be her only high school art course (AP music theory could also fulfill the art category).
*e.g. California and South Dakota public universities; Arizona public universities require either a year of art or a year of career / technical education.
However, if she is not interested in the AP courses offered, then replacing ceramics with those may make the year less pleasant.
If she is concerned about counselor rating for “most demanding schedule” and for academic achievement (in the counselor’s school report used by some colleges), she may want to ask her counselor if possible changes to her schedule will affect those ratings.
