'22 CA STEM kid interested in chances and more safety schools to look into

Cal Poly SLO is the only CSU that uses 9-11th grades as stated in original post, so using the Rogerhub calculator, you need to calculate your SLO GPA also.

I think you gauged your chances well with the exception of Cal Poly SLO which I would put more on the Reach side vs. Target. General Engineering at SLO will probably be a slightly easier admit than Computer Engineering based on the SLO target projections.

Cal Poly Pomona looks like a solid Target school.

EECS and MET are Very Competitive at UCB. GTech I believe is a Reach school as an OOS applicant.

Best of luck and I am sure you will have several acceptances from which to choose.
