Intelegent, I think that TTI has a full program. Excelsior reqcuires that composition must be taken through them, you could CLEP the other core recquirements, and then you could take the Jewish Subject Exams for the rest.
Frum33, if your Yeshiva is accreditted by AARTS, Excelsior will accept your credits. Even if they don’t, there are a large amount of JSE’s that you should be familiar with.
