I dedicated a whole paragraph to the skills I have developed from my AS levels. As I've studied "essay" subjects and I'm applying for Law I basically said that they have taught me powers of analysis and evaluation skills. In addition AS Level has taught me how to manage time effectively, etc, etc.
What subjects have you studied? It's probably a good idea to state that you've developed the key skills, ability to communicate articulately and confidently, time management, etc.
