Link to original post : Rankk Solving Statistics

Funny, I go on a trip to Penghu followed by a four-day science camp and also get dragged into drawing classes and some sort of movie advising joint, and this is what I decide to blog about. Since it’s summer, I went back to Rankk and solved stuff. This is lots of fun if you’re […]
