As a rule, Pre-College grades do not count towards high school requirements, AP credit, and high school GPA. However, for the most accurate answer, the student should contact the College/Career counseling office at their high school. Upon successful completion of the Pre-College course/s, your student will receive college credit (recorded on an official transcript) at UC Berkeley, which they will report when completing college applications.
The credits earned by a Pre-College Scholar may be transferrable to your future undergraduate institution college/university, pending the approval of the receiving institution. Here is a Course Transfer Tool for Berkeley Summer Sessions courses.
