【推理类英语听力】29（在线收听）

It's been a difficult four years, but I'm finally done. I changed my major three times. I thought I wanted to become a doctor, but I realized I'm not interested in medicine. The courses were hard and not interesting to me. I already have my first interview for a computer programmer job next week. I am looking forward to receiving my diploma tomorrow.

What is the man looking forward to?

 High school graduation

 College graduation

 Retirement

 Getting married
