To any undergraduate student that wants to pursue graduate school, my best advice would be to study hard, celebrate your academic victories, and don't get caught up on your failures. Everybody has a story of a course they wish they did better in, or a midterm/exam that was an unexpected curveball, but as long as you learn from your past and keep pushing forward, things will work out for the better.
Do your research: on the lab, on the faculty, on the department and on the city itself. There are so many different programs/departments and it's imperative you know what you're getting into. Speak to students that are currently in the lab or have recently graduated to get an idea of how things work. There are going to be some tough times in your program and you want to make sure you're surrounded by people that want to support you and help you get through, to be successful.
My advisor was more like my mentor. He is very open, honest and helpful, which made me very comfortable to express my ideas and also to discuss different issues concerning my academic life.
The University of Guelph is a small family in itself with a lot of support to facilitate different types of lifestyles. My ability to feel safe and learn without worry is something I have admired.
I recommend taking the time to thoroughly research potential graduate programs and supervisors to find one that is a great fit. It is important to work with a supervisor whose interests align with your own, as passion for your research will help you succeed in academia, especially when things get tough! If you are passionate about reproductive health and fertility, I wholeheartedly recommend the MBS program.
Always ask for help. When in doubt, ask; When not in doubt, ask. Enrolment in graduate courses can be very small, and grad life can sometimes feel isolating; so, try to form great bonds with other grad students. You have a lot in common! Try to take some time off to have fun, and when you inevitably encounter students pulling a tractor in September, do the opposite of what I did; and be cool! If you can, participate in the 3-minute thesis competition (3MT); it's a lot of fun!
This is a program that is very responsive to student needs, so if you have a question or want to pursue a line of discussion, be sure to ask! There is a considerable commitment to participants' career and personal growth, as well as to the more formal education elements. I appreciated that "all-around" approach.
