During registration of SAT on checkout stage an error appeared saying something about errors in application, now I can’t choose the exact date that I needed (8th march), can I create new college board account and wouldn’t it break the rules and regulations of the site?
Don’t create a new account. Go back and fix the errors.
I checked everything and all things were correct, I think there might be the problems because I specified that im in 11th grade (in which I am), but site insisted on 12th grade (which aren’t a thing in my country), I marked that my info is correct, but it probably can cause troubles
