Looping through sets in order

You could keep the data in an array quizSets with one entry for each set 
with the values 0...N quizzes.
So the value of quizSets[set] is zero to the number of quizzes in that 
set, indicating the last one done. It is now easy to know how many sets 
you have, whether any quizzes in it have been attempted and which was 
the last one done for that set. A saved variable or custom property can 
hold which was the last set attempted.

If you have varying counts of quizzes in sets then you can test for the 
possibility of another one using "if there is..." on a file name. If you 
allow people to take quizzes randomly in a set then extend the array to 
two keys [set,quiz] with value done or not done.

The principles here are much the same as Kurt's suggestion but the code 
may be a little more compact and is quite general in what it will handle.

You may need to split and combine the array if writing/reading to file 
data. I tend to keep these sorts of things in a custom property of a 
saveable stack.
