I submitted my application already, but after looking through other's stats, it seems like a lot of applicants have varying extracurricular activities. Taking on a leadership role in a club/organization requires a certain dedication of time commitment and I just couldn't make that commitment because my work obligations were more important for me throughout the school year. My extracurricular activities merely include volunteering at the hospital, free dental clinic, tutoring high school students, and MOM projects. NO leadership or research experience. These activities were manageable since I didn't have to stick with a strict time schedule or be in circumstances where I am obligated to attend every meeting(i.e. pre-dent club president/secretary). My GPA is a 3.5(3.4 science) and I have completed 140 hours of coursework(Bio major/Chem minor). I'm taking the DAT soon and have been scoring in the 20's on practice exams although it isn't predictive of what I will achieve on the real exam, it gives me a bit of a rough estimate. Since I don't have any leadership and research experience, will this significantly lower my chances of being accepted given that my academic stats are also pretty average?
