Instance Method Details

#position ⇒ Object

Position mask:

  • We use 7 blocks of 2 numbers for:

    subject, resource_types, grades (average if more than one), module, unit,
lesson, num_of_grades

  • The last position is the number of different grades covered, i.e: a resource with 3 different grades show after one with 2, (more specific at the top, more generic at the bottom)
