There are queries coming from the School Loop user's about Google drive submissions where they would like to know if they can submit files from the Google drive installed on their computer? Here is a link to know more about how to Submit Work Online
The answer is Yes and No. Files with the .gdoc and .gsheet extension may be turned in but will be useful to your teacher only if they also have Google Drive installed on their computer and you've given your teacher permission to view that file. Please check with your teacher about submitting these types of files. It may be best if you first download your Google Document as a PDF or other common file type and submit that instead.
You can also submit a link directly to the online file. Your teacher can open it as long as you've shared it in terms of granting permissions to view.
