You probably were the most "with it" person at your high school. When you arrive at CMU, this will not be true -- not by any factor of your own, but because there will be many folks with a huge diversity of experiences. There will be people who have done what you have. There will be people who haven't, but have done something else just as cool. There will be people who haven't done either, and will power their way through the curriculum anyway, taking every opportunity to learn new stuff on the side.

Be ready for that, because it'll be a big hit to take. (For me, it sure was.)

But, the other side of it is this: absence or presence of past experience, in a structured class environment, need not necessarily be a predictor of academic performance. There is all the reason in the world to bring in a diverse assortment of people from wide backgrounds. You have a very strong classical "rounded high school" background, to be sure; but, make sure you understand also that there is much more out there than the classic rounding-out of extra-curriculars! There is a whole wide world about us.

Either way, your site is certainly interesting. I'm not sure how much it will influence our dear admissions department, but best of luck to you!

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?
