Is graphic design a good subject to take ...?
...for GCSE? I've got to choose between graphic design, textiles, food tech, control technology and resistant materials. I'm doing my GCSEs early and I don't know if this is a good subject to pick.

Also, what jobs can you get from it?
Do you think it's a good idea?
Thanks, I'm pretty confused :L
