That question totally makes sense. Here's a breakdown of our review. 50% of your score comes from your academics (25% science, 25% last 45). We only look at your cumulative score to make sure you meet our requirement of a 2.50 or above. This review is done by our team in the admissions office.
Your application will then move on to our admissions committee. Their review will make up the other 50% of your score. The committee will not see your GPA. They review all essays, experiences, awards and honors, letters of recommendation, etc.
Because we take both components into consideration, a student's high committee score can make up for a lower score on the academic review or vice versa.
