I just began dental school and was having some struggles in one or two classes. I know I won't get straight A's, and I'm sure I will NOT be at the top of my class. Is all hope lost when it comes to specializing then? I want to be involved in student organizations and extra-curriculars, but do those not matter in an application if your grades aren't the best of the best? I know it's too early to be thinking about this, but if it's really not worth the effort, I want to spend my resources learning how to become the best dentist I can be rather than trying to memorize mostly useless information that will have no application when I am practicing.
