i am just starting to look into business school and mba progs. i cant afford the really expensive programs but i also dont want to get burned by a sscam school. are there any obvious signs of a scam MBA?

i have found a few i think...
- they dont ask/care about your lack of work experience
- there is no photo of the actual campus or the students, just cheesy stock photographs instead
- they give you your payment options like paypal right there on the homepage
