In summer 2013, Manhattan College introduced an online summer "bridge to calculus" course for incoming first-year students in science, engineering, and mathematics education who marginally did not receive a calculus recommendation based on a mathematics placement test. In this paper, we describe the development of the bridge course and demonstrate statistically that this course continues to prepare its students for Calculus at a level comparable to those who took a full semester of Precalculus, yet at a significantly lower cost in terms of both time and money.
