To add on what @mikemac has posted, the majority of CSU’s also require Junior level status as a transfer so 60 semester/90 quarter units.
I also agree that attending a California community college and then transferring into a CSU or UC would be a good option but you might want to finish out the rest of this year at your current college and then start this summer at a CC.
UC TAG requires you attend a California CC with the completion of at least 30 semester/45 quarter units by time of transfer however, if applying for Fall 2023, then the TAG application must be submitted September 2023, so getting started at a CA CC sooner than later is an advantage. (Something to consider).

Best of luck with your decision.
