Hi Michael,
Sorry, I was in a rush to go start painting my new workshop interior and an hour into it, I suddenly remembered that I forgot the part about needing to do something about the review. Glad you figured something out on your own.
We're also considering putting all of the questions into a single quiz, and somehow grouping the pages. - You can create a multiple page quiz and then when editing the quiz, for each page you can add the number of random questions you want from the applicable question category.
page 1 - add x number of English questions
page 2 - add x number of Chinese questions
page 3 - add 35/50 French questions
page 4 - add x number of ? questions
page 5 - add x number of ?? questions
You can even add a description question as the first question on each page with any "Notes" or "Directions" for that portion of the quiz.
