I agree with sushilife above. Your response is straight-to-the-point, but needs to show more to leave a lasting impact on readers. Right now, it sounds like a bullet list.
Take this line for example:
It is very rewarding being able to help others having trouble with their academic courses.
Try add some depth; how is it rewarding? Could you illustrate it?
Or, you could try cutting out this line:
The subjects I mentor my fellow students in include general chemistry, biology, and every level of math until Calculus II.
(A detailed list of what subjects you teach is not really necessary)
That way, your sentences flow more smoothly.
It is very rewarding being able to help others having trouble with their academic courses.
The subjects I mentor my fellow students in include general chemistry, biology, and every level of math until Calculus II. To me, tutoring is a way of relearning everything and
a way to change the way I see the subject in different ways(You may want to revise this; that's too many "way"s in the same sentence) .
This is very beneficial and it is the reason why I enjoy doing it(Again, try to show how it is beneficial and how you enjoy it) . By Tutoring, I am able to interact with different students and learn how to communicate better. Doing so, I also learn different teaching methods and different ways to get my point straight with different subjects."
Hope this helps!
