So I'm currently trying some problems in the test room. Do they cater these to your rank or do they vary a lot in strength because I'm doing terrible , but it's a lot of fun. Also the applet says something about a short explanation to problem answers. Can these actually be seen, I can't seem to see them.

Bumping this up because I too can't see the answers or the explanations.

Worse, the Strength Test page has an "excercises" section that says, "Here are the problems you got wrong. Practice and improve weak parts of the test result." But when I try to click on a section like "Judgment" where I did particularly badly, the applet says there are no more problems.

How can one get back to the old problems one has already tried?
