Welcome to the homepage for McGill Math 139 Calculus with PreCalculus (Fall 2018), at Jacobâ€™s Math Help Desk!

All the content taught in Math139.com sessions has been catered specifically for Math 139 students at McGill and has helped thousands of them understand the material and succeed in this class.

Beyond the Weekly Mastery Lectures that I offer, I will also run, if there is sufficient interest, WebWork Workshops, Midterm Mastery Prep and Final Exam Mastery Prep.
