Graphic Design - How tough to get in?

I was accepted into the graphic design program for BU for 2017-2018-
my grades are
GPA: 3.8
Old SAT: 2010
For the portfolio though… I don’t have a bad portfolio but I don’t consider it as professional so I guess an average portfolio? Most of my work is done with traditional materials such as watercolor and colored pencil. I also only have 2 digital art pieces and 2 graphic design pieces (logo and stationary). Oh and I described each art piece in the space that they have in slideroom (such as why and how). I hope this helps!
