Ratings do not come with college degrees... however, at most colleges that offer flight programs (Embry-Riddle, Saint Louis U, etc) you will receive credit for whatever ratings yuo have prior to registering at the school.
FOr example, at my school (Saint Louis U), if you come in with a private with instrument, multi, and complex ratings, then you get credit for eight classes (four ground classes, four flight "labs") But you still have to take lots of other classes to get a degree. This is assuming you are majoring in Aviation Science/Pro. Pilot. If you choose a different major, then the flight credits would only count as electives.
