📗 [1 points] Why are you submitting this survey? Did not attend one or both of the lectures this week. Attended both lectures but missed some questions on TopHat. Attended the lectures but TopHat did not work. Want to submit anonymous feedback.
Note: if you selected the third (please also email me) or forth choice, you only have to complete the last question.
