"Though it has been 15 years since I was in school, I do take CPE courses to maintain my CPA credential. I recently took one for the changes in the tax laws that are being implemented and it was really interesting. I was able to go back to my office and prep for these changes by changing the tax allocations to which our company was contributing to prevent owing more than we should. By implementing the changes when I did, it saved the company five thousand dollars in taxes owed."

Be honest. If you didn't have a favorite then pick the class you did the best in. If college was 15 years ago, then talk about some of your most important learning experiences with the updated laws and regulations that have been enacted.

You don't want to sound like your bragging, but you do want to brag a little. This is a good time to casually mention the grade you got in that class or the way you were able to implement what you learned into your work.

"My favorite class was the auditing course and lab. It was like a big jigsaw puzzle finding all the pieces and putting them in a specific order to ensure everything is accurate. The formulas you get to use will show you if their accountants did the math correctly, which is always fun. I really enjoy math and finding things other people missed. That's why I believe I'll be a great auditor!"
