Several years ago my daughter got into the CMU program but chose to go elsewhere. We found that you need about a 1250+ for CR and Math SATs and about a 3.5 unweighted GPA or better. In addition, the portfolio evaluation is about half of the admission decision. Follow CMU's requirements for the portfolio to the letter. When they say that want a lot of drawing from observation,they mean it. Don't submit lots of photos, graphic arts, or other types of steps in lieu of what is required.
