Finished my certificate course - what worked for you?

I finished a short course in San Diego while looking for work as a web developer. There are 7 people counting on me, so I am trying to be careful. I already had an interview request. Any tips for using it on my résumé?

Thanks for writing this out. I went through something close to it 9 months ago, and it settled down once I kept a simple log of every call and form.
