Start by moving the first section's text up higher, so it doesn't start obscured by the background.
Then, remove the annoying JavaScript from the downvote button that prevents you from clicking it. (You might also consider not using Facebook's thumb icon for this.)
Finally, reconsider why you want to attend CMU. "Code" is what 1st year students learn. Computer Science is what 2nd, 3rd, and 4th year students study. You've not told us how you will benefit CMU, or how attending CMU will improve you, but that you can write code. Good for you (sincerely) - but that's not what a Computer Science education is all about. You want to learn CS, but why? What are your goals?
