TECEP rules to follow?

[pws]

From what I've read on TECEP, there are a few things to watch out for. 

On TESU's policy page for TECEP, it is written:

- You must test by the last day of the 12-week term in which you register. There are no extensions for TECEP exams.
[...]

Retests
- If you do not pass a TECEP exam the first time, you can take it one more time in a different term.
- To test a second time you must register in a new term and pay the registration fee.

I'm not sure about the following:

• If you have only a 12-week term left for your degree, if you fail it means you can't retest, correct?
  
• Is there a limit for the number of TECEP you can take during the 12-week term, or during a month?
  
• Are there any other important rules for TECEP that you need to watch out for?
