Works something like a passworded page - you have to type the secret word

in this case, the word is: troy

A view + source will display the secret word and the destination. (Most people don't look!)

It could be modified by having the student type something from the keyboard (answer) and taken to a response page. Probably more useful with short-answer questions (true-false) or Multiple Choice (a-b-c-d) type questions with linking to a feedback page.

Where can you go to get a good college education?
