I don't know if it was just my school or my teacher or the course itself but....
If your thinking of choosing Graphic Products for GCSE and it's AQA I really don't recommend you study it.
From my own experience, the coursework is horrible (again i don't know if it's the school, the course, or just me) but it took so long, there is so much evaluation, designing boring stuff, it just wasn't fun at all. The coursework is a huge proportion of the grade so it takes up the majority of the two years (or at least it did for us) and by the time we'd finished we had very little time to revise for the actual exam, we all got stressed, and foremost we all got the blame for what little time we had.
It's probably down to a poor teaching schedule from our DT department, but if i were you I wouldn't recommend choosing it, it wasn't interesting at all and I dreaded every lesson. Fortunately, I thought the paper was quiet easy, so hopefully I'll still get a good grade with that and the coursework combined.
