There’s a really good article here on Affirmative Action that would be of interest to any edexcel American students with respect to the race in America topic.

Affirmative Action has been shaped by the courts more than any other branch in recent decades, and this case highlights how this is still true. Opinion on AA is usually viewed through a left/right prism, with liberals arguing it is still necessary, and those on the right advocating a dismantling of the system on the basis that it is un-American and possibly should have never been introduced in the first place. There are of course neutrals who share these views, or take the stance that some sort of AA is necessary but should perhaps focus on class rather than race.

Anyway, the article is here and provides a good summary of how the courts have interpreted AA in colleges.
