IF the admission algorithm is largely the same as it was last they publicly discussed it in 2013, some of that matters and some of it doesn’t.
Calculate her GPA using the CSU calculator and 9-11 grades. That’s the only GPA that matters. It was capped at 4.20 in 2013, with everything above that rounded down to 4.20. Some suspect that it has been increased, or even that the cap has been eliminated. The important point being though, a student with less than a 4.0 unweighted can still hit the max in their algorithm.
APs don’t matter per se. They do boost the weighting in the GPA, but in the calculator they are capped at 8 semesters. A student with 4 APs is seen as the same as a student with 12.
STEM ECs make no difference.
Getting back East will be easier than it looks on paper. There are all sorts of student ride shares to SF, with easy drop offs at SFO.
Before you write it off, look at the linked thread below. They still use the MCA, but it’s probably been changed a little. It’ll give you a general idea though.
Lastly, it’s worth considering starting in General Engineering. It’s assumed that they are unsure of what they want to do, so the process for changing majors is a little easier and the barriers are a little lower. It’s an easier admit than either ME or CS.
Best of luck! It’s a fun time!!!
