In this article, we describe the process of developing and implementing a collection of courses designed to allow mathematics students an opportunity to demonstrate proficiency and pass a course that extends past the scheduled end of the term. Extending student work beyond the end of a given semester potentially alleviates some of the time constraints on students that typically lead to failure and gives them in some cases a second chance to develop understanding of concepts that were previously obstructions to success. We find that in all courses the extension increases the success of students in the primary course, and that success in the next course is comparable for these students as well.
