I've never critiqued any Submissions so maby take this with a grain of salt but here is what I think:

  • it's up to you if you want to greet yourself it's just formality. You can start of by congratulating them on their progress and say you are going to point out things that you think could be improved or are useful to know.

Personally, I think it's best to give the feedback in the order that the corresponding lesson has assigned it to, that makes it easier to follow along.

As an example if you critique lesson 1 you say what what you think about the supper imposed lines exercise first and than work your way down the list of assignments.

  • Next you should definitely point out what's good and what's bad, both are valuable in there own right and give insight on what to improve.

  • Unfortunately I don't know what a legitimate reason would be to suggest for someone to repeat a lesson, but as a rule of thumb it's best to just let them move on after you gave them the feedback as Uncomfortable say's it in lesson 0 on the topic of grinding.

  • lastly I think it's ok to give someone encouragement, I guess it's a formality again I wouldn't overthink it to much

I hope this helped, as a last tip you can look at other critiques (especially the official ones) for better reference
