That's its home page, but I suppose the submitter chose the other URL because it gets you into the details straightaway, which an HN audience tends to appreciate. Both links are good.

Not exactly. It's linking to the old SAT practice material that's for the old (current) SAT exam. The new material, for the upcoming 2016 exam, which was just launched today, is available at:

https://www.khanacademy.org/sat

If you want to "get into the details" you'll need to be logged in and complete the onboarding, through this URL:

https://www.khanacademy.org/mission/sat

I mean, linking to the current URL is fine, but it's not what was actually released nor is it representative of the new content.

Ok thanks, that's dispositive. Url changed from https://www.khanacademy.org/test-prep/sat.

(Sorry khirasaki; I get what you meant now.)

Haha, good. I downloaded the sample test from OP's link and was reading through it, and my main response was "yeah I'd hardly call this a redesign…"
