One of my coursemates was also on an IF trip, under the Macchi hood, with the last approach being an NDB into Gin Gin. It starts at 20,000' and the MDA is 1100'. Bloggs was under some pressure to get it right, and was a bit rushed as he started the outbound leg and descent, idle / speedbrake / 220kt. Done his 2 minutes, turn to intercept inbound track, oops, here's 1100', level off, must not descend below it, that's an instant failure. Track to overhead the Gin Gin NDB.
Instructor takes over, Bloggs relaxes a little, until instructor rolls inverted and starts a pull-through. Bloggs thinks he is about to die, you can't do that from 1100', and reaches for the seat pan handle. Hang on, he won't intentionally kill me, wait and see what happens. Then the realisation that he had levelled out at 11,000'.
Bloggs went on to be an Air Vice Marshal.
