Here is something different: I wrote a piece on exam-taking tips. It's on a new website, Cafe, which has lots of good (non-quant) reads. The motivation for the piece is my observation that most American students are not taught how...

I like the clever way they tell the story. It’s a straightforward series of graphs but the reader has to figure out where to click and what to do, which makes the experience feel more like a voyage of discovery.

Don’t, don’t, don’t, don’t . . . We’re brothers of the same mind, unblind

Hype can be irritating but sometimes it’s necessary to get people’s attention (as in the example pictured above).
