There will be 28 lectures given by the instructors, each lasting 2 class hours. The actual timing of lectures may differ slightly from section to section because of university holidays, but the total number is the same for all sections.

The table below is a rough guideline for the content of course lectures. Professors may reorder their lectures as necessary/desired. Section and page numbers below are from the textbook, Elementary Differential Equations and Boundary Value Problems, Boyce and DiPrima, 9th ed., 2010.

Exam dates will be determined by the administration and are currently only approximate guesses.
