I am designing an English test for my students. However, I'm not a native speaker.
I want to design a quiz that can judge a student's result not only by his/her answers, but also by how much time he/she spent in that quiz.
What's the best way to express this?
Can I say
The result(s) may change according to how much time you spend in the quiz
(BTW, should we say "result" or "results" for a quiz?)
