From their site:
The biology and chemistry courses must include laboratory exercises. In other words, 1 year of Chemistry lab, 1 year of Organic Chemistry lab, and 1 year of Biology lab are required in addition to their corresponding lecture courses. Calculus, statistics, or other college level mathematics, biochemistry, epidemiology, and molecular biology are recommended but not required.
However, I was looking at last year's BU thread and a lot of people that took 2 quarters were in the same situation submitted, but just commented on it in the additional info box. So I dunno if its okay. They also require 1 year of biology lab, which I only have 2 quarters of.
