This essay is not bad at all.
I would change the beginning--they know the prompt. Do not waste words restating the prompt. Just jump right in with how learning is important to you.
Besides that, there are some awkward phrasings.
In tenth grade was the first time I received my first F and I thought it was the end of the world.
"I received my first F in tenth grade, and thought it was the end of the world."
"7 years later" should be spelled out: "seven years later." However, the bit about your mom's education is a bit irrelevant. Maybe just make it more concise. "My mother is a very strong-willed person, raising me herself. Her education came to a halt when I was born, but it was important enough to her that she enrolled again seven years later, and instilled those same values in me." Something like that!
"A" becomes repetitive. Switch some of "A's came easy" or "to do my best and make A's" with alternate words such as "great grades" or "the top of the class," etc.
The end also needs to be connected to learning more. Did you learn how to become a good leader or what? It basically sounds like you were trying to find a way to add in some of your extracurriculars...but they already know those! If you choose to keep that in there, make sure you connect it, and spell out "four" and "two."
This is an awesome start though!
