Academic achievement is weighed heavily by the admissions committee.
Keep in mind, though, that grades by themselves don't tell the full story. Faculty recommendations are also very important in helping admissions committee members to appreciate and assess your abilities. Admissions committees also pay attention to the difficulty of courses you select and where you took them. As the application picture stands at present, two out of three candidates to allopathic medical schools will not be admitted, even though they may be very qualified applicants. While most Wesleyan graduates are highly competitive applicants, you should apply only when you are personally ready and a strong candidate.
