He is very good at making sure that you understand the material beyond just knowing how to do problems, and challenges you to think about the concepts. He also makes the material feel relevant as to why you need to learn it for future classes, and your career. He is also very personable, and makes it fun to learn the material. I would certainly recommend Peter to anyone!
The book is well written and is largely self-sufficient, but Philip helped me get oriented to using it efficiently, and I appreciate being able to ask Philip for clarification of concepts and for additional info about computer science that isn't covered in the book. I also appreciate Philip's encouraging me to manage my life well and to work diligently so that I will be able to achieve my career goals.
I am new to R coding and analysis and had difficulty on one of the assignments. Serge looked at my code and made recommendations to assist me. My course is a Data Science class that jumped into R on day 1. He has been extremely helpful in getting me up to speed and I am much more comfortable with it now.
