***More than a hundred of the ostraca found at Athribis are covered in repetitive writing exercises, with the same characters written over and over and over again, on the front and the back ***

Sounds like what is often referred to as a 'A-B-C-D-ery', a school where writing and penmanship were taught and practiced. Such documents are found at Qumran, home to the Dead Sea Scrolls, and other scholarly centers in the ancient world.
