No, I am the one who is sorry. Hope that I didn't offend. To answer your question with an analogy, I had few A's in my Biology classes (mostly B's) and even a couple of C's in Chemistry. There were a few things that helped me, though. First, I took Calculus in high school then the AP test. So, I got the credit for taking it without getting a grade (which almost definitely would NOT have been an A). Secondly, to show that I wasn't just plain bad in Chemistry I have an advanced degree in Biochemistry.
Again, your grades represent only a part of your entire application (as they only represent a very small part of you!). If you feel that your grades aren't top-notch, first try to improve them and second, try to improve your application in other ways. For example, I have a fair amount of volunteer work. I loved doing it, it was fun, I didn't have the responsibilities of a paid employee and I was treated exceptionally well (I worked for free, after all). Also, I did biomedical research. Again, it was fun and I enjoyed doing it. Find something that you are good at, in which you can excel. Schools like to see leadership and dedication to medicine.
Good Luck!
