c) How to submit answers (participating institutions only)

The last prompt will ask whether you would like to submit the log of your tutorial session to Google Forms so that your instructor may evaluate your progress. This feature is only available for students from participating institutions.

If you choose ‘yes’, a form will open in your web browser. Complete and submit the form.

You can submit multiple attempts and the best attempt will be graded. You will receive full marks as long as you answered all questions (i.e. did not use ‘skip’). If you used ‘skip’ because you could not answer a question, please contact your instructor for advice.
