UC’s use 13 areas of criteria for their application review and a few B’s will not take out of the running for any of the UC’s for Engineering even though they are GPA focused.
You need to calculate your 3 UC GPA’s using this calculator: GPA Calculator for the University of California – RogerHub
Below are the UC admit rates which are not major specific. For Engineering, the admit rates will be much more competitive but have you an idea of which Engineering you will be applying?
2022 Admit rates based on the Capped weighted UC GPA.
| Campus | 4.00+ | 3.70-3.99 | 3.30-3.69 | 3.00-3.29 |
|---|---|---|---|---|
| Berkeley | 17% | 3% | 1% | 0% |
| Davis | 58% | 20% | 5% | 2% |

| San Diego | 37% | 8% | 1% | 0% |
| Santa Barbara | 41% | 8% | 3% | 0% |
| Santa Cruz | 69% | 45% | 16% | 4% |
As stated by @ucbalumnus, Cal states are also a great option for Engineering but they are even more GPA focused since they do not consider PIQ’s (essays) or EC’s.
An Engineering degree is highly marketable so you do not need to attend a top school to be successful post grad.
Best of luck.
