How to submit assignment of c2w1

So in c1, while doing weekly assignments there was a launch option of workbook, in c2 which is not available. Now how to submit assignments from c2. Do I upload the full Google Collab file, split it, or anything else?

Hi Esrak. You might have figured this out already. For other learners who might have the same question: You can click the Create Submission button and you will be prompted for the files to submit. For week 1, that would be the notebook and the history file. Hope this helps.
