IB MATHEMATICS SL
Course Description: IB Mathematics SL is an advanced study of mathematics, designed to prepare the student for the IB Math SL Exam and additional Calculus, either AP Calculus AB or BC. It is a rigorous course of study specifically designed for that student who expects to go on to study subjects which have significant mathematical content. The class will include a portfolio, consisting of two assignments, one on mathematical investigation and the other on mathematical modelling.
