How colleges calculate GPA: Most colleges ignore non-academic courses like PE, Health, or Driver Ed and recalculate your GPA using core subjects only, which is exactly what this calculator does. Rules vary: the UC system includes performing arts, some schools weigh Honors differently, and a few use their own scale entirely. Use this as a solid working estimate; the number a specific college uses may differ slightly.

Enter your core academic courses only: Math, English, Science, Social Studies, and Foreign Language. Skip non-academic classes like PE, Health, Driver Ed, or Teacher Assist.

GPA Questions, Answered

Which courses should I include?

Include only your core academic courses: Math, English, Science, Social Studies, and Foreign Language. Skip PE, Health, Driver Ed, Study Hall, or Teacher Assist. College admissions offices typically recalculate GPA using only academic subjects.

What's the difference between unweighted and weighted GPA?

Unweighted GPA uses a straight 4.0 scale regardless of course difficulty. Weighted GPA adds +1.0 for AP or IB courses (capped at 5.0). A big gap between the two tells colleges you took a rigorous schedule, which they view very favorably.

Full Year vs. 1 Semester. Does it matter?

Yes. A full-year course counts as 1 credit and carries twice the weight of a semester course (0.5 credits). Most core courses are full year, but some schools offer semester-length electives within the core subjects.

How accurate is this calculator?

Most colleges recalculate GPA using core academic courses only, so this calculator is often closer to what an admissions office sees than the GPA on your school transcript. Rules vary: the UC system includes performing arts, some schools weigh Honors differently, and a few use their own scale. Treat this as a solid working estimate, not a guaranteed final number.
