And exactly this is going to be worse without standardized tests

[Nate Silver @NateSilver538]

Not sure how you can look at this data, ostensibly be interested in either meritocracy or equality, and want to move away from standardized tests. It's the subjective measures that are most slanted in favor of the rich kids.

If penguin eggs are boiled, the albumen does not whiten but remains translucent this is because penguin eggs have more of a glycoprotein called penalalbumin which would normally help the eggs survive the cold.

Before you begin your thinkpiece, the Supreme Court DID NOT strike down Affirmative Action

Admission preferences for legacies, donors, employee families and special recommendations are still allowed

The Court struck down Affirmative Action For everyone except WHITE PEOPLE

[dr. alina von davier @AlinaVdav]

I’ve always supported the #AffirmativeAction. People need role models. They need to #belong. And everyone benefits from the #diversity of experiences.
