<p>I really screwed up senior year. My mid-year grades are:</p>
<p>AP Biology- B
AP Chemistry- B+
AP Gov- A+
AP Lit- B+
AP Calc- B</p>
<p>How much do these grades hurt my chances? Are senior grades weighted heavily? I wished I tried harder; i barely put any effort into any of these classes. My grades up untill senior year were all A's with a few A+'s dispersed here and there. I took all honors and AP courses.</p>
<p>Math Level II: 780
Biology M- 750
US History- 720</p>
<p>Are my chances in jeopardy? I applied to the faculty of sciences and the inter-faculty of arts and sciences. My senior grades do not reflect my aptitude in math and science. Also, does McGill look at class rank or just GPA (just curious because my rank prob dropped with my senior grades)?</p>
<p>The min. requirements is a B+ average for grades 10-12 and you have around that for senior year, plus your SAT scores are way above the minimum. You definitely have a solid chance.</p>
