Do some research.
Speak to students currently at those institutions and see what the course is really like, don't just take the black and white of the course brochure as gospel.
Then give some design companies a call. See what sort of people they hire. I expect, more often than not, they will tell you they hire based on an applicants portfolio, not their grades or paperwork.
Perhaps consider which course is going to give the most diversity, which one will let you experiment and find your niche as a designer, rather than one that boots you out the door in 3 years with a certificate but no real experience in the reality of design.
Also, take every chance to make contact with practicing designers. Contacts lead to opportunities.
