One key difference is that the Division III coach can only run practices during the assigned season. Thus, many Division III athletes have the opportunity to play two or more sports, but only if they choose to play. During the season, your coach can require 20 hours a week of your time for practice. A scheduled competition counts as 3 hours of practice time no matter how long it takes to get there or how long your warm up is. You will carry an average of 15 hours of class time, approximately five classes depending on the curriculum, per academic session.
Some colleges are semester and others are trimesters.
If you are a science major expect to spend additional time in the lab and with discussion groups. The key to your success will be how well you use your down time. If you have time between classes, plan to study or run errands during that break. Get to know your teachers so that when you do miss class for a game, or you need to request time outside their scheduled office hours, they may be more flexible towards your circumstances. Find a private study place where you won't be easily disturbed.
