Feedback to Netstation

[Robert F. Buzan]

Anyone out there know how to send something to Netstation that indicates whether
they received "correct" or "incorrect" feedback?  I need to segment on the
feedback based on whether they answered right or wrong, and I'm stumped.  

**Extra Credit:  There are two ways to answer incorrectly: 1) answer
incorrectly, and 2) answer too late.  Any chance to be able to segment the
feedback based on this difference?

Thanks for thinking about my problem and for any responses.
