101f Calculus with Precalculus I Designed for students who enter Colby with insufficient precalculus background for the standard calculus sequence. It is expected that all students who complete Mathematics 101 will enroll in Mathematics 102 in the following January.

Students electing this course must complete the mathematics placement questionnaire prior to registration. Three credit hours. RHODES
