(The done page shows the badges for an account.)
If you want to see where you are on the way to earning a badge, look at the bottom of your done page -- there's a little table which summarizes the number of problems done per section, so you can see where you are. Solving 3 problems in a section earns one star.
I'm thinking about a "challenge" feature where CodingBat could present a series of blank problems (ignoring if you've solved it before) over a few minutes to practice or show mastery of a particular badge. You can imagine employers using a feature like this to enable candidates to show that they can do the badges they claim.
Practice, practice, practice!
