Don’t know if you are still looking for suggestions but off late I have been playing around with 2 relatively easy to use platforms surveyanyplace.com
and riddle.com.

Both of them have some cool intuitive quiz building functionality and a whole lot of features including personalising quiz results and sending it out to the participants either to inform them, enhance their understanding or give them tips and tricks to embed their knowledge further.

Both are subscription based and pretty easy to use.

All the best.
