Margarita, is after-school wrong altogether? Should I delete it?

Why, Uly? I think it’s even better than my translation. I also wanted to know your opinion about my version. 😊

Thank you))) There’s a bit of a difference between the two. EXTRACURRICULAR activities are things you do IN ADDITION to your normal school work, for example sports, clubs, journalism, etc. AFTER-SCHOOL activities are things that kids do when they get out of school for the day, such as going to a study center, playing on a soccer team (away from school), being on a swim team, volunteering at the library, etc.

Yes. In Russian I would rather say “ внеклассные мероприятия «
than “внеурочные мероприятия»

For which one?

for extracurricular activities.

Here you can read about the difference between « внеклассные занятия и « внеурочные занятия». https://kotuch.ru/4518/chem-otlichaetsya-vneurochnaya-deyatelnost-vneklassnoj
