<p>I would try to get them in at Cal and/or during summer school either at Cal or at your local school.
Definitely verify, in writing, and if you would get aid for a 3rd year, just do that, which would also give you more time to connect with profs for LORS. It will be tough at Cal to connect well enough with the premed prereq profs such that they could write a strong LOR. My DDs chem prof was teaching 1200+ students that term, even with office hours one would struggle to find a personal connection
The math can usually be calc I plus stats.</p>
