This is the lab manual for either Biology 103 or 105 for the University of WI- La Crosse. At the bookstore the manual sells for 37.50 and the Quick Study Guide for 5.95. I would be willing to meet you on campus (as I am still a student there) and sell both of them for 30.00 or best offer! That saves you 13.45 from the bookstore. Message me if you're interested!
