I wonder what my future holds.
I wonder if I can keep up my good work in Karate class. I really need to move up my rank. 'Yellow belt' is a bit shameful for a 15 year old, even if they're beginners.
I wonder if I can up my grade for the classes that I didn't do well in.
I wonder if I try hard enough, whether or not I'd make it onto the honor roll.
I wonder if I am any good in acting as I'm said to be a pretty good singer.
