As a Canadian I never took anything like the SAT. I don’t quite get why it exists. Or why people are convinced it needs to exist. Most of the world does fine without it.
That being said, I support whatever helps empower the diminished classes and helps quash the undeserved power of those born into money. …And in that case, the SAT might make a lot of sense now that I think of it.
Even if your teenage years were a quagmire and you have no grades to show for it, a single test can still open you up to academic opportunities.
