In your original code, the inner loop looped over correct_questions, but in
the menu items, you did not reference the correct_questions item and
instead referenced the question item from the outer loop -- that is why you
saw the same menu item repeated multiple times.

Why use .as_dict()? If you leave it as a Rows object, you can refer to
row.question instead of having to do correct_questions[row]['question'].
Also, what is all_questions? Do they come from another db table, and if so,
is it linked to db.questions_answered? Perhaps you could just do a single
db query (via a join) to get the data you need.

If nothing returns, then presumable question['diff_level'] never equals
100, as both if statements include that condition. Also, rather than
nesting the second if inside an else, you can simply use an elif.
