Yes Blinko, just this 'For me it was Geometry, including sines, cosines, logarithms, blah, blah, blah. What was that about?? Pointless unless you end up as a civil engineer, I'd have thought.'
I tried to ask the physics teacher to explain what it was for ... and the reply was 'don't ask questions, just do it- when you become a civil engineer you will know what it is for' - and as I had no intention whatsoever in becoming one - that was it.
For the Baccalauréat at 18, we had to continue all the subjects to the end (unlike the UK where most finish with just 3 very narrow subjects) - so my scientific clever big brother taught me just enough to pass the maths, physics and chemistry exams by the skin of my teeth. And did very well in the rest.
Forgot all about it the minute I got the results - what a waste of energy and time, when I could have learnt another couple of languages instead, that are REALLY useful.
