I'm not American, but I have seen a lot of my friends apply for American universities. Personally, I think the whole admission process is super messed up. In most places one would take a nation/international examination and based on the score of that exam one would enter. In the US one has to pay "college counselors" and various middle men for handling all sorts of things. I don;t see how removing SATs would make it "fairer" for students from less well to do backgrounds. Removing college counselors would though.

This is not to say I would agree with the fact that the SATs/ACTs are good. To be fair as far as exams go these exams have a lot of loop holes. I have seen people who can't speak proper English get perfect scores on these exams by memorizing hard words. The mathematics section is a bit of a standing joke in many Asian countries. It is almost impossible for a high school student to get less than the full score in many countries as it would not be possible to pass other national/international boards.

In all honesty, rather than scrap ACT/SAT, one probably should review these exams. It is possible for one to design an exam such that private tuition doesn't give too much of an advantage.
