Exams and Homework
There will be two midterms: LOCATION: KRAN G016; TIME: 8pm-9pm February 13 and 6:30pm-7:30pm March 30, and one final: LOCATION: WTHR 104; TIME: 3:30pm-5:30pm May 4 . No notes, books, or calculators will be allowed during exams. Each midterm will be worth 100 points, the final will be worth 200 points, and the homework grade will be scaled to 100 points (75 points for WebAssign and 25 points for hand-graded homework), making a total of 500 points for the whole course. To compensate no late homework policy, the lowest three of WebAssign and two of hand-graded homework will be dropped.
