How do I calculate my CC GPA to UC GPA?

I currently have a 3.4 GPA at my CC, and I recently got accepted to UCD. When I looked at the " Course credit summary" in my portal for UCD it says I have a 3.38. Then when I looked at the UC Apply website It gives directions on how to calculate a UC GPA and when I calculated it manually it came out to 3.42. I’m confused about which one is correct. I TAGed UCSB and need a 3.4 for the guarantee so I’m a bit stressed, does anyone have any insight on this?

Are some courses not UC transferable?

Any P/NP scores that might be confusing it?

Yes, I have some courses not transferable with a P/NP, but I did not account for those in my total amount of credits when doing the calculations.

Sometimes they don’t match when it’s auto-calculated and it’s corrected later (or maybe not). Perhaps you should contact UCSB.
