Suddenly my classical rating is increasing or decreasing by amounts after each game and there's a question mark next to the number. What's going on with this.
You only played 9 rated games in the Classical time format. As such, your rating is provisional (indicated by the question mark), and the "swings" after each game you play are consequently larger. Once you play a certain number of games in this format (20?), the question mark will disappear and the "swings" will stabilize as your rating stabilizes as well.
