I’m going to respond as a career teacher. Keep your debt to a minimum. If you know you want to teach chemistry in CA, then choose a CA college for your undergrad work. Look for the public universities with education programs. You will likely need to major in chemistry and get your education credits as well.
Do you qualify for the Calgrant? Of so, consider a CSU to which you can commute. Or consider a UC where you can commute. Those will be your most inexpensive options, most likely.
