well thanks everyone, I would like you to know that my parent’s yearly income is $17000 (approx) and so I would only be studying on financial aids, on on-campus works and educational loans. I am from India and in my country good colleges for aerospace(IITs, IIST, IISc, BIT ranchi, etc) do not accept students after 2 years from high school. And there are few colleges here that do accept such students, but I have seen many of their graduates with the degree in hands and now are struggling to find a job. And for the SATs I estimated it from raw scores of few past years real tests and some mock tests that I solved from various SAT prep courses (Sparknotes, Barron’s, priceton_review ). And I would apply in at least 20-30 colleges.
And for the redesigned SAT I don’t think It would be much different in difficulty level ,etc.
