"I am the only one in my family to apply for a degree" - following the prompt right?

Describe the world you come from - for example, your family, community or school - and tell us how your world has shaped your dreams and aspirations.

(this is the the unfinsh first rough draft i just want to know am i in right track, )

My life has been a challenge in every way and second since the day I came to US. I am the only one in my family tree to ever apply to a university. My mom who can't say a word in English discontinued her education after high school in Afghanistan. My dad gave up after two years of community college; he was struggling with learning English. Since the day I enter High school, my ultimate goal was to attend college. The problem was obstacle after obstacle. First, I had to develop my knowledge from Afghanistan standard to the US standard. Unfortunately, the gap between Afghanistan standard, where eighty percent of people are illiterate and the US standard is huge that I had to do more than study to overcome this situation....

Except from some basic errors like "since the day I came to the US"
you seem to be on the right track regarding your topic. But adding more detail about your family
would be a good thing to add and describing its effect on you about neither on them being in a college. Do they support the idea you are the only one who would be going to college? stuff like that is what a University wants to see. Also "tell us how your world has shaped your dreams and aspirations", so try to include what your main dream is instead of just attending a University. such as long term career plans after you finish? etc

thank you for the advice

Great job, Mustafa. And let me tell you a writing secret everyone should know:
Before you decide to write, think of what effect you want to have on the reader.

Before you do anything, think about what you want to make happen.

Do you want the reader to feel inspired because of your struggle to overcome your obstacles and succeed?

One good way to make a reader feel inspired is to discuss the subject that you feel strongly about. Your inspiration is contagious, and readers appreciate feeling inspired.

I think what you have so far is great! Continue with focus on your goal.
