allow P's to skip and come back to ?'s

I am trying to make a math test on the computer to be as much like real life as possible- where participants completing the test would have the option of skipping the more difficult questions (if they wish). In addition to this, I would like the questionnaire (of 18 problems) to cycle back through the skipped items (but not the already answered questions) once the original end of the questionnaire is reached. Also, I'd like for p's to work for an entire 20 minutes on the task, but I would also like them to know how much time they have remaining so they can budget their time wisely. I know how to do each of these separately, but I don't know how to do them in tandem (e.g. dXXX or d-XXX in the experiment file for the particular questionnaire, but i can't get dXXX, d-XXX both working together.

In order to do all of this, I am hoping you can show me how to do the following: (1) how I make a "skip and come back later" option; (2) how I can get media lab to cycle back through the skipped questions until time has run out; and (3) how I can put a forced time interval on a specific questionnaire (with multiple questions in it) and still show P's how much time they have left to work.
