The policy makes a lot of sense and it is commendable for UC to actually do that. Seems it can relieve motivation for many grade gaming tactics.
Alas, not completely so. Students may still game for the grade, with the UC GPA rule instead their own high school’s.
I cannot not think of how my d’s sophomore and junior course selection will affect her UC GPA - I reviewed her Algebra II curriculum and seems it covers a lot of advanced concepts that I only learned in my own calculus class. Perhaps it is really viable for her to skip normal calculus and take an AP Calculus instead, which will significantly raise her UC Uncapped Weighted gpa.
Or take that fully online Summer General Psychology course at a CC, since she has already learned the materials many times over from other college psychology and The Great Courses psychology courses and will need minimal review to ace it.
