Unfortunatly Swiss that is how the system works. It does not measure intelligence so much as a willingness to work hard.
And yes, the ACT and SAT are both by "non-profit" companies that make a large amount of profit. That is not the issue here.
The issue is whether you will work hard to get the score (and grades) you need. The American system of education does not teach knowledge, it teaches people how to learn, and more importantly, how to work hard. Because without hard work people do not succeed in the "real world." (As if school is somehow less real)
