I have a suggestion, wchich might be helpful. Wouldn't it be good, to add information next to the contest name in the schedule, whether it is rated or not? A good example is educational round: Educational Codeforces Round 51 (Rated for Div. 2).
This way you would avoid all the questions rated or not if such an information is not in the announcement. But even better — it would help some people plan their time. For example I see a few contests right now. One of them is 5 hours long. It is divided between div1 and div2 so it might be rated, but the duration is pretty unusual, so I'm not sure. Besides there is also the elimination round of the Technocup and I also do not know whether it is going to be rated or not.
I would like to take part in rated contests but I also have some other things to do and that information would help me organise my time.
