  • Experimenting with the Khan Academy API

    In the last month or so, I've managed to more than triple the number of Earth badges I have on Khan Academy just by focussing on getting the Sub-light Speed and 299,792,458 Meters per Second badges, particularly on the simple exercises. I worked out on which exercises to focus by creating a spreadsheet of all the exercises and all the badges I had for each exercise. I filled out the spreadsheet with a combination of screen-scraping and manual data-entry.
