Exam 1: Thursday, Feb. 13, in class.

What I skipped: a more formal discussion on complex numbers (pp.12-15); cells, Cantor sets (because we are not covering measure in this course), connected sets.
Practice questions
The rules have been relaxed: Aside from the book or printed pages from it, you can use unlimited number of notes, including the ones you took in class. No other books or printed pages from other sourses, like from other books, online materials, etc. No electronic devices of any sort.

Exam 2: Thursday, April 3, in class.

Final exam: Thu 05/08, 3:30p - 5:30p, KRAN G018

Course grade

Your course grade will be determined using the following distribution: HW: 1/3; Midterm 1/6 each (1/3 total); Final: 1/3.
