Correct me if I’m wrong, but with this list, you won’t need any LORs. Also the Cal States tend to be less interested in ECs and more interested in stats. Both SDSU and UCSD are hard admits (and your GPA is on the low side for them), but your likelies and safety look pretty good, as long as you would be happy to go attend one of them if your reaches don’t pan out.
California is quite generous with aid - depending on income, make sure you apply for the Cal grant and, also depending on income, you may also qualify for the middle class scholarship. You can use those at any California school.
