If you mean with "design side of things" the art side, then it's totally fine if your drawing skills aren't up to speed. Most of our classes involve digital art, but you're extremely valuable if you know 3D art as well, which you will learn during the study.
If you mean with "design side of things" the experience design, then you don't need to know any drawing skills. I do recommend checking out some UI designing if you're interested in that.
Hope this helps!
