Be patient with yourself. As a student your job is to learn, and by necessity, fail. Solving the problem and having the right answer isn't always the same thing.
A graduate student at the University of Guelph is a lot of work, but it is very rewarding. My schedule was even more flexible now than when I was an undergraduate student, which is very important because you have to make time for everything. There are classes and seminars, research, meetings, Teaching Assistantship(s), mentoring, and readings happening constantly. If you plan things well, you can get involved on campus or have a social life, too!
My advice for prospective grad students is to reach out to people. When I was looking at the CDE program, I reached out to a couple of graduated students in different fields to talk about their experience in the program. This information was very valuable and helped me to make a confident choice. If you have any questions about the program or my experience please feel welcome to reach out.
Guelph is an amazing school academically and socially. You will be able to conduct cutting-edge research, surrounded by people who passionate, intelligent and supportive. There are so many social events and opportunities so don't be nervous to join clubs, teams or come out to social events!
