Completed training while job hunting - what worked for you?

After 16 weeks of evening classes I have a new certificate. There are 15 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 10 months ago, and it settled down once I kept a simple log of every call and form.
