Hello! third year here! I had around 3-4 C's ( vertebra biology, ochem, calculus, biophysics) as well as a 2 D's (calculus and Ochem: retook but did not replace my grades). When I was accepted I did not redo nor did I got for more schooling when I was first wait listed. Instead I actually focused more on my career that I already had in the industry. I focused a lot on my own personal growth and during my second interview I talked a lot about my experiences I had since my last application. They really just look for you to be well rounded, typically people say once you make it to the interview they will weigh how you did heavily to see if you woud fit with the class they are forming as well as what your end goals are to keep the class diverse (GP vs exotic vs large animal etc.).
