Hey—well done on completing your AS levels.
How about including skills, and any volunteering you've done? (If you haven't really volunteered before, maybe you could look into it. There are so many places in need of volunteers, and you could even apply some of your interests. I had some fun helping out at the cathedral, and learned a lot about its history!)
A list of skills might not be a bad idea if you know what to include. When my team at work were recruiting my successor recently, they were keen to see Adobe InDesign mentioned on the CVs as it's a huge part of the job.
Good luck!
