While you can trust the class to take the survey, you should place a trap question to throw out the survey if someone did not really pay attention while taking the survey. Our group trusted everyone to but then we had the problem where one/more individuals did not take the time to complete the survey. The results were skewed and we could tell because the person(s) just pressed 1 all the way down the survey in a span of a few minutes. Good luck on your results.
