Instead of evensong being a break off of school, you have to go sit in an overheated chapel and listen to things that you don't find interesting at all. I would much rather have classes. I find in evensong, that when I do try to pay attention we seem to go over the same topic over and over again. Plus, we already spend 1 hour a week learning everything we need to know.
Another reason evensong is boring is because we can't ask questions. In every class we get to raise our hand and ask a question about something we don't understand. In evensong, if your confused then your out of luck. This makes learning in evensong a lot more difficult.
To conclude, I think evensong is a waste of time and that the time should be used for our regular class time schedule.
