Personally, though, I just think standardized testing sucks. There is not possibly way, nor is there any logical reasons why your life's academic achievements should be summed up in a 4 hour test. It is largely based on how one is feeling that day as well. If you are tired or sick, your 're screwed. I'm glad to see that they are losing importance. Just look at the grades instead.
Not to mention, the richer you are, the better you tend to do on the test. People with more money can hire a tutor for the test, and take it more times than people with very little. In my opinion, it is a bit, but not always, biased in that regard.
Plus who wants to get up a 6:00 on a weekend to go take a freaking 4 hour test? No one, that's who.
