There are a quite a few grammatical erros. For example, I set up
theLianhegonghui Volunteer League in
grade 10
the grade to
draw more attention and offer more chances for my schoolmates to
become involved incommunity
serviceand volunteer activities
, and; I served as the president of the SUS for a year.
What is the SUS? I'm guessing it's the same thing as the Lianhegonghui Volunteer Leaguem, but you should clarify this.
Also, most importantly, you didn't describe what this activity meant to you, what you learned from it, or how it changed you. I know the prompt says "elaborate" on an activity, but that doesn't mean just describe *what* it is. You could get all this information from, say, a generic pamphlet about the organization. Make it more personal.
