I'm hoping that I can get some honest answers here. I'll start off by saying that I wanted to be a doctor since I was very small, and that it is like a dream job for me. I have a passion for biology and health. But the only thing standing in my way is grades. I am not a bad student but I'm not a great great student either. Right now I am in grade 11 and I study in Ontario, Canada. These are the classes I currently have, I don't know whether these marks are good: Grade 11 University Biology - 92% Grade 11 University Physics - 82% Grade 11 Univerisity English - 84% Grade 12 Univeristy Advance Functions (math) - 62% My average come out to an 80%. I have very high standards, and right now I feel my marks are very low. As you can see my math mark is 62% and I myself is shocked because I NEVER got below 75% in math, this is the first time. Will this affect my chances of getting into a good university? I have one more math course to take before I enter univeristy, It is Calculus and Vectors. So my main question is, Do I have the grades to become a doctor?
