How hard is it to get into Tyler School of Arts

I’m going to be applying in about 8 months and I’m very scared that I won’t get in because I don’t think my portfolio is going to be great. I know how to draw but I haven’t take official classes and I have so many other things to focus on this year, idk how I’m going to construct a full portfolio. In case you are wondering I want to be major in Graphic and Interactive design.
