Need Advice

Ok guys so I have a dilemma. I am applying for the 2008 cycle. I had a low undergrad gpa about 3.2-3.3. I am now enrolled in an Master program and I have about a 3.85. I am taking the MCATS after the summer and I am finishing pre reqs over the summer. I have tons of medical rotations and medical experience and good letters of recc. I need to know if I have a legitimate shot at an American Med school. I am really worried because I had 4 withdrawls during undergrad. I am having a strong graduate career and I am hoping that it will give me a fighting chance. I also have a long resume with tons of leadership roles and membership in alot of organizations. Tell me what you think guys. Any help will be appreciated.
