### Quiz #2 Prep Session

**Saturday Feb. 14th, 5:00-7:00pm (M3-37A; $25/$20*)**: this 2h session will whip through the concepts and theory included in the second quiz and focus on solving a number of highly representative problems based on quizzes from the previous years (drawing on a bank of >10 years): substitution; by-parts (and combinations of both); trig-integrals & volumes of revolution.
