That Mystifying UK School System

"Did you know that you are now an established O level set text?"

[Presumably one or more of Alexander's plays are being used in the O level test for "English" (?)]

"The O-level (Ordinary Level) is a subject-based qualification, usually taken at the age of fifteen/sixteen, conferred as part of the General Certificate of Education (GCE).
It was introduced as part of British educational reform in the 1950s alongside the more in-depth and academically rigorous A-level (Advanced Level). England, Wales and Northern Ireland replaced O-levels with GCSE exams in 1988.

The O-level was predominantly exam-based. This was advantageous for students in part-time or evening education. There was no summative "school certificate": each subject was a separate O-level in its own right.
O levels exams are often required as predecessors to A levels and by many employers as a minimum qualification for employment. A-level exams are the minimum entrance qualification required by UK universities."
