6. First of all you are doing very well in school sports and the chess club.

✔ Corrected: *First of all, you are doing very well in school, sports, and the chess club.*

- Add a comma after the introductory phrase "First of all."
- "School" is likely meant as a separate item, so we add commas to list: "school," "sports," and "chess club."
- Include the Oxford comma before "and."

> Note: If "school sports" is meant as one unit (e.g., athletic teams), then it would be:
> *"First of all, you are doing very well in school sports and the chess club."*
> But since "sports" and "chess club" are both activities, it's better to treat them as separate items.
