Everything, in order

The Fall 2026 calendar

Quizzes are in Tuesday recitation, timed, no calculator. Dates and lesson splits are transcribed from the department's own calendar — not from a previous semester.

Three windows have no quiz. Lessons 14–16 (tangent planes, max/min) fall between Quiz 5 and Midterm 1. Lessons 29–30 (Green's theorem, curl and divergence) fall between Quiz 9 and Midterm 2. Lessons 34–37 (Stokes, divergence theorem) come after the last quiz and are on the final only. Nothing paces you through those, which is where the grade goes.
