'daughter of two immigrant parents' - why i want to go to college

Being a daughter of two immigrant parents , at a young age i knew to value of higher education. In my culture your parent always want you to become more successful than them. so with that mentality ever since i was youngr ive away dream about going to college. once i started to attend high school , getting the grades to attend high school was my main focus. even though thru my high school ive gotten distracted and havent been able to achive my academic excellence that Ive been looking for, but it just made me strive for the goal of college even more. now that i am a senior Ive gotten more serious.

ive awaydream about going to college change it to "I have always dreamed about going to college."
"thru my high school ive gotten distracted" change it to "Through high school i have gotten distracted"
" Ive been looking for" change it to "I have been looking for"
" Ive gotten more serious." change it to " I have become more serious and determined "

College essay on immigration is often used topic, so your essay must standout from others writing about immigration.
"In my culture, your parent always want you to become more successful than them."
This sentence is a little awkward. Rather than putting third person's view, try to use first person.

There are some grammar issues in your essay, such as:
youngr - younger
thru - through

also, rather than writing haven't, use have not, and I've to I have. It sounds more professional and plus, you can make your essay longer.

Hope this helps!
Good luck!
