Neutral & rec confirmed (...I'm not sure what I was thinking at the time, besides maybe just seniority and not having a reason to object, but you weren't lying that I did).
All of the things that people are objecting for were last year, and six months is a lot—15-year-old me was horribly ashamed of everything I did when I was 14, which is about the age range that "student" would suggest. I can't believe 2019 was that long ago.
However, I can't seem to come up with a reason for a vouch proper (perhaps it's just that I wasn't on at the right time for the positive things @redeastwood#19271 mentions).
Just don't be on for five hours every day—even if it doesn't lead you to get disinterested/bored within a week, there's no way that's not going to affect your grades, and the six-hour activity requirement is monthly (15 minutes times 30 is more than enough).
