I don’t think you’re eligible for TAG. And for UCR, you would need a 3.5 in Major prep to do TAG for business. Google “UC TAG matrix” and you will find the requirements for TAG for each UC that offers it.
I say apply if you want really want to leave where ever you are at, but have some other schools in mind too. The worst they can say is no.
Will you have all your major prep done by the end of spring?
