This is what I see when I look over your post.
The colleges in the US will see the same thing.
You want a full ride because you haven’t done anything?
I don’t know what you’ve heard about the US higher education system, but the colleges and universities have very limited funds for non-residents. The funds that they do have tend to target those students who have gone beyond the “norm”.
They expect:
High GPA’s
High SAT’s
High rigor
High involvement in the community over time.
You want a US college to fund you now because you “didn’t know your purpose”, you “didn’t get the best education” and you “didn’t understand things fully” and now everything has changed, correct?
Computer engineering is a very tough and competitive field. Every school only has so much room for students in that field of study.
The schools look for FIT and may not always take the “best” students but accept those students who have historically shown a record of EFFORT and community involvement during their high school years, as presented by their letters of recommendation by teachers, administrators, and work supervisors. How would you classify your performance?
I don’t know what to tell you other than knowing that your being an international student, requesting funding, gives you less than 1% chance of being admitted to any university.
Your chances are even lower because of your record of your HS performance, as reported by you, less than stellar.
Apply, but it sounds like there will be a lot of blank spaces in the app.
Plus, you need to grasp the idea that admission to a US college is not about what you want, it’s about what the colleges need, want, and fit their criteria.
