-French Club: The hours reflected in the Activities section for French Club were based mostly off of contributions from my 12th grade year. In the previous years, French Club was not as active, as it had different leadership.
Does this look bad? should I add it or not?
I would suggest leaving it out. It’s just a minor logistical note. It does not ADD anything about YOU. If you are going to use the additional info section, use it to reveal more about you that isn’t apparent from the rest of your application.
Now if the club is more active because YOU, as part of the new leadership, are making it so, THAT would be worth mentioning.
Just leave it. It tells admission officers nothing about you or your contribution to the French Club. Minor details like that don’t really matter.
