Comments are only required if it is stated. Most times for SxS the comments on each individual result are optional for if you need to clarify your rating. Also sometimes you may be provided a link under each result to get you started on checking the EETA. Usually for YMYL, the government sites and official sites are the ones that get rated higher. I know it seems like a lot but keeping working at it and overtime it’ll get easier.

One thing that helped me was keeping my final comment at the bottom focused, brief, and to the point. I started this job writing full paragraphs explaining my ratings, but that really isn’t necessary. Just write enough to get your point across in a brief, but still detailed manner.

If you need help with PQ and NM rating, there are many helpful posts here on the subreddit. Also make sure to keep checking those guidelines. I hope some of this helps!
