Should I even bother applying?

<p>I'm currently a sophomore at UMass Amherst and for as long as I can remember I wanted to go to Boston University or Northeastern. I'm a Microbiology major on a Pre-Med track and my gpa is not good. I currently have a 3.18. Is there anything I can do to help my chances? Do taking classes at community college over winter break do anything? Is there anything I can do currently to help my chances?</p>
