On Reading after Immigrating to America ..

I suggest going to high school in America and then going directly to college. It's no big deal to fail a year.

If you finish high school in Canada and then go to the United States, I don't know how to calculate the credits.

If you pass ECE calculation, your score below 80 is C, so it is difficult for you to get into a good university in the United States, let alone a scholarship.

After finishing high school in the United States, you will have American credits and go directly to American universities. It is easier to go to college in American high school than to finish high school in another country and then transfer to college.
