Who told you that? Have you contacted UCR or any other UCs? What about Cal States? Surely you can be given a second chance. Talk to every admissions office you can including your community college. BTW, some community colleges in California are beginning to grant 4 year degrees. http://www.sdmesa.edu/academics/bachelors-degree/
I don’t know if there are others, but maybe look into that.
Thank you for your service, by the way. I hope it works out for you.
