Test questions

[Scrapper1]

As I mentioned, I took the PAVO test recently. I was allowed to keep the test and the correct answers as a study aid. This is the first time I've been allowed to do this, and frankly, it's awesome.

But I do have several questions that I'd like to ask about things that still aren't exactly clear to me. But I also don't want to post the exact questions if there are some people who still haven't taken the test yet.

Anybody know if the test is still being administered?

Here's one that I can ask without giving away the question (I think). Could someone just point me to the rule that discusses when time-outs or subs can NOT be granted? It seems that different requests are only granted at different times, and I can't figure it out, or find it in the Interruptions rule.
