Chances for NC schools&NYU!

Hi guys! I know you guys have viewed alot of these discussion and i do appreciated those of you who commented and gave advice to people! Below are my infos; Chapel Hill is my #1 choice so far, then Duke(which is really hard to get it), NYU, Wake forest, Davison, and lastly Upenn which i am not putting any hopes on now after i received my sat scores.

Took subject test math I and got a 550, which i was very disappointed and i am going to take it over again to bring it up; didn’t send this score to chapel hill tho
Class rank- 19 out of 368

Work- i work as a cashier in a restaurant for two years now

I have difficulty writing strong essays but will definitely try my best
Questions:
What are the advantages of early decision? If i get rejected can i apply again during regular decision?
Do colleges look at ethnicity? I am Asian, not very smart kind of asian tho
Does private tutor helps? If so, could you guys recommend some tutors?
Anyone knows if Davison gives lots of scholarships?
It looks like i dont have any special talents and my sat is extremely low, are there any chances of getting accepted by far?
Thank you! !!!

Forgot to mention: English is not my first language but i’ve lived in us for more than 5 years now. Do i have to take Toefl to prove that my english is not bad?
