“Reach” was going to be my guess, but @Gumbymom knows the public university system in California far, far, far better than I do.
If you want to keep the option open to go to medical school, then you should budget for a full 8 years with the last 4 being quite expensive. Doctors are relatively decently paid and can handle some debt. However, even doctors have trouble paying off the cost of medical school. The less debt the better. If you could graduate with an MD and no debt that would be even better if it were possible. Of course this means that if you can get a bachelor’s degree with no debt and money left in the college fund this might be helpful down the road.
The University of Oregon is very good for premed and might save you a bundle being in-state. As you might already know, Oregon State University has a very good DVM program. The pre-vet classes overlap a lot with premed classes (one daughter is currently studying for a DVM, and very seriously considered Oregon State – she was in a lot of the same classes as premed students for her bachelor’s degree).
I meant to add: Congratulations on your very good results to date, which to me appears to be well earned through your hard work through high school.
