I am sure you will be successful with a proactive attitude like this, and if you work hard you will do well. Some pro advice above I see from someone in the know.
Is your personal statement all about C. Sci?
For example, it could be the place where you stand out from the other candidates, you are memorable, tutors are looking for someone that will be pleasant to be with for 3 years and coach-able.
Demonstrate you help grannies with PC's. Do charity runs dressed as a chicken for those less fortunate, that you are a task completer e.g. you researched and built your own PC or similar. You have other interest besides PC's. A special interest, for example I built my own arcade machine to play arcade games. You complete projects and don't give up. Demonstrate that you have a track record of finishing what you start. Go and work voluntarily in a PC role. Teach some kids to do something with PCs.
Stand out. Think general and specific.
Best of luck with the Boolean thingy o_0.
