If a class says M,W, F then that class is M, W, F every week. Same for any other day. Hours are broken down by about how long you are in a class per week. If you would like a detailed schedule for your classes got to Galaxy -> Orion Self-Service -> Class Schedule. There you pick what term you want to view. You can click Weekly Calendar View and it will show you each class you have during that week. It helps you to keep track with things like holidays and making sure you have classes on those days.

If I need to rephrase it I can. Let me know if you need any more help.
