I was just asked to simplify SQRT(27) three times in a row. Some filtering to prevent the same question being asked consecutively would be nice. Harder but more reassuring would be to make sure that the same question can't be used twice to achieve a "proficient" rating. I've seen the same-problem-repeats on several exercises, so this is a feature that should probably be implemented across exercises.

Thank you!
