I only teach asynchronously online. I prerecord videos for the courses and collect homework from the students weekly, then provide personalized feedback, and help students successfully learn the material through resubmission of their work. I answer questions sent by email within 48 hours.
Anyone who wishes to learn from one of my prior courses can click on the link below to access all the materials and videos. Anyone who has completed Linear Algebra and Vector Calculus may wish to check out my Youtube Channel. Questions by email are welcome!
A note on Impressing Professors and seeking letters of recommendation.
