iCal HW

I'm in school and get lots of different class calendars that tell me what is going on in what class and what homework/reading i need to do. I got sick of looking around for these ugly pieces of paper and decided to consolidate it all into one calendar on iCal. It hasn't worked out so well. I put in my schedule and couldn't find a way to add in what homework i have for each class on the calendar itself. I was hoping for a way to add it to the class on the schedule for each day, and the only way i could figure out for it to show when I looked at my day was for me to put in the homework under the location section of the events. Anyway, is there an easier way to do this?
