Looks like the last few pages of this thread are proof that we've all turned into our parents

Agree with pretty much everything that's been said...and I think HOF and Michael's willingness to listen and comment intelligently show how useful an education is.
Don't worry HOF most of us felt the same as you do when we were your age.
I do wish I'd been able to do a lot better in secondary school...partly my own fault as I'd already been accepted for the RAF before my exams so didn't give a stuff and partly other domestic carp. But my schooling was useful in my career...not just lists of facts and figures but the ability to analyse a mass of information and extract what I needed, all the essay writing helped when I had to write up annual reports on staff and compile job descriptions etc and trust me there is heaps and heaps of maths in a war
I know it's easier said than done but learn now while you don't have to pay for it. I started doing an Open Uni course a few years ago but stopped because it just got ridiculously expensive.
Good luck to you both with your exams...don't underestimate yourselves...I reckon most on here have been impressed by your contributions.
