How do I become a Graphic Designer?
I'm 16 now, taking A Level subjects Art, Graphics and Physics. Although I regret not taking Graphics for GCSE, I am still willing to learn as much as I can in 6th form about Graphics because I feel this is the area I would like to work in some day. I'd just like to know if these subjects are suitable ones that will lead me into the 'graphic design' area, because I like the idea of working for a company who does graphics for films or games etc. Anyone is who does this kind of job please give me your opinion, thanks.
