The clinical experience won't make up for a lower GPA but it can help sway a decision. I have a lower GPA as well and have to work on it.
Many people applying these days have hundreds of hours of research, clinical exp, publications, etc..so it is really competative. GPA is a key sorting factor along with MCAT. The fact that you were an athlete will make you stand out and will definately help you.
For my gpa issue, I am taking classes in fall and spring and will continue to take them unless I get into a school this cycle
. I would suggest the same for you. If you pull off some A's in undergrad/grad level classes and send them to schools after taking them it makes a really difference.
Also you should stay in contact with schools you are most interested in. Call them with questions or email them about the program, I have heard that some programs take note to this because you show heavy interest. Or update your app with any new research or activities. I have heard people that were waiting on a school, updated an app with a publication, then got interview the next day.
So just keep doing what your doing and do more! and apply to alot of schools. GL
