Thanks for your reply.
To my knowledge, using Google doc service for courses does not violate any EPFL principle or regulation (If it does violate, please let me know).
You can use the .odt file for the future homework that relate to google doc service (unless we otherwise specify). You can simply download .odt files without any login on Google. If you are in areas like Mainland China or North Korea where the Google service is unavailable, we will figure out how to help you to finish the homework.
