Make an appointment with an advisor at your current college and ask these questions. Make sure you have all the necessary coursework. Call the admissions office at the colleges and ask to speak to an admissions officer in transfers. Or better, get the name and email one of them, explaining what you’ve said here. Ask them what they recommend. There will be a section on the app to explain extenuating circumstances and they will also notice your recent upward trend.
You need to add other colleges to your list. It is not a good idea to pin all your hopes on two colleges that are extremely selective. The goal is a degree and other UCs and CSUs offer degrees in applied mathematics. Don’t run the risk of sabotaging your goals by thinking only two colleges are worthy.
