README: Do the exercises as you come across them in the lessons, not in the order shown here. This list is for quick access, if you already know the exercise you are looking for.

If you are a student looking for your submissions, check "Your submissions" in the Your stuff menu.

Sort by the "Order in book" column to see where the exercise appears in the course. Click the column header to do that.
