One of physics teachers was a nice enough guy (seemed like a bit of an alcy, but can't really blame him), but had a pretty weird concept of constructive work. In other words, one lesson he'd bitch about how little of the course we'd completed, and then the next lesson we'd spend the whole hour cutting out and sticking physics 'puzzles' (eg match the title (like hookes law) to the definition)... Unfortunately in Y12 the other teacher was a newly qualified and very smart, and so assumed we knew everything, and got a bit grumpy when we didn't, and in Y13 his replacement was middle aged ex navy lass, who was pretty much teaching herself the course at the same time as she was teaching us... The worst bit was she was soo bloody lovely that you couldn't ever be pissed off at her, until you got home, tried to do an exam question, and realised it was nothing like what we'd been 'taught'...
