Gary Rubinstein has been watching the progress of the 83 students who were in Success Academy’s first class.

By the time they reached fourth grade, their number had shrunk to 59.

By ninth grade, there were 26.

A few months ago, it appeared there would be 17 graduates.

But, wait, Eva handed out only 16 diplomas!

Where is the missing scholar?

If you have any clues, please let Gary know or post them here.
