I handed this sheet out too late last year, and so didn't promote and stress effectively enough this aspect of their studying:
This year, I took some time in class today to stress each bullet. Basically, the theme was, "do something that will realistically work for you", and "show me that you have put some thought into this", and "if you find it's not working, then revise your schedule on the fly".
I personally know how it is that time just slips away if I don't have a firm plan of action on what to do when.
Hopefully, this will help the little boooooogers.
