Use:

when gf clicked
delete (all v) of [done v]
set [score v] to [0]
set [question# v] to [1]
repeat (length of [questions v])
repeat until <not<[done v] contains (question#)> >
set [question# v] to (pick random (1) to (length of [questions v]) )
end
ask (item (question#) of [questions v]) and wait
if <(answer)=(item (question#) of [questions v])>
change [score v] by (1)
add (question#) to [done v]
say [Correct.] for (2) secs
else
say [Wrong.] for (2) secs

Trinary,

I have the exact same need but your answer is too advanced for me just now.

I want to do a quiz which isn't over until all questions have been answered
correctly.

If a student gets one wrong, it goes back into the pile and re-emerges at random
later on. If a student gets one right, that question is eliminated and will not be re-asked.

Could you give a pseudo code description of how that should be tackled?

Well, you'd first want to check if the answer was right. 
Then, if it was, you delete it from a list of questions. Otherwise, save it in a variable, delete it from the list, then

insert (old question) at (any v) of [questions v]
