BIOS 100 - Exam II - Fall, 2003 Name: ___________________________________ Michael Muller, Instructor 22 October, 2003 TA: ______________________________________

The exam consists of 50 multiple guess questions and six pages. Please bubble in your name, last name first. Please be sure you use the name with which you are registered here at U IC and not a nickname. If you only learn one thing from college, please learn that whenever you fill out one of these forms, you should use a #2 pencil. Pen just won't work. Really, it won't. Good luck!
