TESC and ACE approved courses...

I emailed TESC and asked them...would you accept ACE approved upper-level courses from American Acadamy of Nutrition (DETC)?
Answer...If you would like us to send you an application for enrollment form, we would be glad to help you with all your questions.
AAA! There are specific courses I want to take at this school, but they are DETC. So...do I have to transfer them to a credit bank (RA) somewhere, then transfer to TESC when I'm ready? or just not take these courses?
On the prospective student helpfulness scale, TESC has been scoring about a 1 with me. And it's a shame because it's the school I ultimately want to go with.
THX!
