In my day - 60s- there were grades 1 to 6 before you failed (7).
and then degrees of failure, 7, 8, 9, then unclassified.
i know as that;s what i got in maths o-level.
the first time, at school, hardly any teaching went on and perhaps one trained teacher.
who left after a short time. and not maths.
it was not the acme of academe.
some years later, i took maths as a private student; by then it had changed to A,B,C being passes.
i was pleased to get a middle pass, B.
the first exam was in a london town hall, v good staff, calm atmosphere, big assembly room, spacious, airy, large clocks either side.
it was a pleasure to attend.
second part was in a modern hotel basement room, cramped, dingy, and no clock. !
i didn't have a watch, as every exam i had ever taken had an official clock.
by then i'd taken numerous inc college and post-grad and work-related.
i was the only person not using a calculator, and had long division and trig going down the edges of the exam paper.
i remember having to do differential calculus, something that looked like a large tongue on a graph.
