Good afternoon, I know it is early in the cycle but I am considering sending update letters to schools that accept them. I have a major weakness in volunteer hours on my application. I have been working on that by volunteering at a local free primary care clinic. I applied with 50 non-clinical volunteer hours, and 5000 paid clinical hours. I have since added 30 hours and will continue to volunteer 5 hours a week. I would also update them with my summer semester grade in human physiology. Is it too early to send an update?
