Worst - and by miles, has to be miserable Coningsby in the early 80s headed by that execrable unit 228 OCU.
Count yourself lucky! 228 was a holiday home compared to that utterly dreadful outfit of the late 1970s, 237 OCU at Honington.
The only place where I ever encountered total contempt, bordering on hatred, towards students.
Fortunately I was chopped and went to the delights of 230 OCU at Scampton, then 3 happy years on the Tin Triangle.
