As a serious piece of advice, if you're super-short on time, make sure you fill in the 3 initial lists: top 15 domestic, top 7 weekends, and top 10 worldwide along with dollar guesses for them. Those three lists are worth potentially as much as every other possible source of points in the entire game, combined. Yes, really.
No, you probably won't do great on the three lists if you do them fast, and answering the other lists and questions is good because it makes you research and think things through.
But if you're short on time, you're better off spending that time on the big points rather than the little points. Plus, you can always look at what other folks have predicted so far. Those predicts might change a bit as guesses get refined, but it gives you an idea of what others are thinking.
