An amazing teacher

I've just received an email from the lecturer of my Machine learning class congratulating me on my completion in week1 review questions. I was so surprise because that is not an automatic email but a true letter to me. That's fantastic because I've never got anything like that from my teachers. This course is a little bit difficult but I always have bunch of helpful peer students, especially my teacher Andrew Ng beside me. So I'm excited to continue this course and hopefully get a certificate at last.
