one requirement on the 'php quiz' homework says to "display the quiz but make it optional". i am not sure how to read this. do we display the quiz, but make taking the quiz optional (not necessary)? or is it viewing the quiz itself (i.e., the questions) that we need to make optional?
You can do it either way. However, you should be clear in your messaging. For ex. if you display the quiz then you may have a msg that says if you are UG1 then the quiz is optional click here to see your table of results or take the quiz and it will be scored along with showing you your table.
If you do not show it say I see you are UG1 please click here for the quiz or here for your table of results.
