Help what are my chances UCR

i just wanted to know what my chances are for getting to UCR.
I am a junior (11) in high school in California. I am a first generation student with low income as well.

I have an overall 3.25 for my gpa (10-11) so far. I have gotten an 1800 in my SATS and will be taking 3 AP classes for senior year as well as completing my business certificate (3 years or more of business classes).

ALSO i have a suspension for threatening a student. (It was a very personal thing). ALSO idk what major to choose, but is it a good idea to choose a major that will make me more likely to get accepted and then swtitch out later?

I also have no extra curriculars.

So what are my chances THANK YOU!
