'not aware of the responsibility' - Common App Short Answer about volunteering

Hi,
I wrote an essay about my volunteering experience.
I have worked on it for hours and I hope you all like them.
Please be generous to make criticisms because I need them.
Thank you in advance.

Prompt: Please briefly elaborate on one of your extracurricular activities or work experiences in the space below (1000 characters)

Simply signing up because of my counselor's suggestion, I was not aware of the responsibility that followed the duty as a member of California Scholarship Federation. After school, I went to ROCK, Reaching Out, Challenging Kids, to help the people who need to raise their grades up to be legible for school activities. Seeing them working after school everyday, I decided to help them the best way I can so that they can enjoy their high school years to the fullest. At first, I was anxious due to my verbal limitation. However, giving explanations of simple algebraic problems and getting to know more of my peers gradually resulted in a sense of achievement and a great boost of confidence in myself. Many times I see my friends whom I worked with, enjoying their time on the dance floor and cheering with their hearts out in the football field. Those moments make all the hours that I spent in the classroom worth my time, and I hope to continue to witness that I can be a great help to others.
