Way back when, longer now than it seems... I had an algebra university class with an all multiple choice final exam.
...I got zero answers wrong on the final. And anyone who did get anything wrong deserved to fail, honestly. Because when your question is "what is X in this equation:", and then it DOESN'T MATTER THE EQUATION, because you can just fill it in with every multiple choice answer and see which works via trial and error.
