I know that on a semester system, 1 year of calculus would be calc I & II. Harvard also requires a year.
If you are applying for 2016 or later at Harvard you don't need a full year of calculus.
http://hms.harvard.edu/departments/admissions/applying/requirements-admission "Although the calculus of derivatives and integration represents important concepts for the precise, quantifiable understanding of dynamic physiological processes and systems,
a full year of calculus focusing on the derivation of biologically low-relevance theorems
is less important than mastery of more relevant algebraic and trigonometric quantitative skills. Still, to prepare adequately for the quantitative reasoning demands of the contemporary medical curriculum and certain medical specialties, to provide analytic perspective and to appreciate the uncertainties in evaluation of biological systems, students are required to have familiarity with calculus. A broader and more flexible range of requirements is encouraged, however, and, given the
importance of statistics for understanding the literature of science and medicine, adequate grounding in statistics is required. Rather than increasing the one year devoted to mathematics preparation, the one-year effort should be more relevant to biology and medicine than the formerly required, traditional, one-year calculus course. Flexibility will be welcome in meeting these requirements (e.g., a semester course in calculus that covers derivatives and integration and a semester course in statistics; a calculus-based physics course and another science course that includes a firm grounding in
biostatistics; or, preferably, a unified two-semester course that covers important, biologically relevant concepts in calculus and statistics)."
