List

Each of 5 schools (A, B, C, D and E) is implementing the same math course this semester, with 35 lessons. There are 30 sections total. The semester is about 3/4 of the way through.

For each section, we record the number of students who are:

  • very ahead (more than 5 lessons ahead)
  • middling (5 lessons ahead to 0 lessons ahead)
  • behind (1 to 5 lessons behind)
  • more behind (6 to 10 lessons behind)
  • very behind (more than 10 lessons behind)
  • completed (finished with the course)

Find it, and tell it visually and, above all, truthfully.
