Chances for Grad School w/ low gpa

<p>I am looking to go get my Masters in Evolutionary Biology or Cancer Biology</p>

<p>Stats:</p>

<p>Junior B.S. Biology major and Biotech minor at top 40 LAC (Top 50 overall according to Forbes)
GPA: 3.0 currently (hopefully 3.1 by end of senior year). Had a 2.5 at end of freshman year so there has been slight improvement.
2 years of Breast Cancer Research. Will end in a publication.
Currently training next research student
Biophysics Research Group member
TA for Evolutionary Biology lab
Supplemental Instructor for General Biology
Started a Biology Club (will be President next year), President of Ping Pong Club (was VP last year)
No GRE yet. Plan on also taking Biology GRE to try to offset my low gpa
Race: African American</p>

<p>So what rankings should I be looking at in terms of US News Biological Science Programs (since it is so popular)? Do I have any shot at an okay university?
Also what consists of Tier 1 (is it 1-50?). I never have figured that one out for grad school.</p>

<p>Thanks a lot people!</p>
