Tracking whether or not a student is indie or not ...

An indie student does not belong to any school sektion.
His console can potentially look different from that of a school student.
Enrollment will impact the flag.

But the biggest impact would be when we stop supporting schools altogether.
Then, we can get rid of this attribute alongwith Quiz, Exam, Worksheets etc.
Blessed will be that day!!
