See the link below. Being in a smaller pool of applicants wanting a small number of spots, your application needs to shine like the stars. They aren’t just letting people in the side door or anything like that. You have time it looks like, but you will need the test scores, step up that GPA and a killer essay that tells a story about why they should offer you one of the coveted transfer spots. I would also encourage you to get involved in something besides that code club. You have to get rid of that idea that it is “too smart and competitive” for you. Remember, it’s a reach for everybody. Best wishes.
