I have a mixed opinion on coursework...I think it's a good idea in general, but obviously is vulnerable to cheating and abuse. I definitely disagree with this new thing that coursework has to be done in controlled conditions under a time limit so teachers can prove it's your own work, even though I suppose it would reduce the risk of cheating. I personally did most of my coursework at home and spent more time on it than teachers say you should, e.g. my friend's ICT teacher told them they should takeabout 1 hour doing each of hardware and software, when it took me the whole evening to do them, around 3 hours on each. Having to do it in controlled conditions would mean that I'd rush it and therefore not produce my best work, and IMO timed conditions defeats the object of coursework because the exam is in timed conditions- coursework is mant to be an extended piece of work that you take your time on and do your own research on...if it's in controlled conditions the course might as well be 100% exam, so I'm glad we missed out on that new regulation.
In some subjects, like English, I think it is a good idea, but in Maths and Sciences it should be scrapped altogether IMO. The science coursework that we have to do is more of an essay writing test than scientific IMO, and in our Core Science GCSE it brought virtually everyone's mark down by a huge amount, bringing some people's mark down by an entire grade. Saying that though, the good thing with coursework is that it gives you reassurance with exams that at least you have x% of the marks and takes the pressure off a bit.
