Organized by Northern/Southern Hemisphere, the space in between representing the equator, each sheet is then placed as closest or furthest away from the equator.
So far, our mystery classes are organized in this way:
Northern Hemisphere: 5, 10, 2, 3, 8, 1, 6 (5 being the place we are guessing is furthest away from the equator, and 6 the one closest to it)
Southern Hemisphere: 4, 9, 7 (4 being closest to the equator, 7 further away)
After reading this past Friday's clues , we have a little bit more of an idea for some of the mystery classes, but nothing sure yet!
