Hi Rusks. I'm a graphic designer, been in the industry 4 years. i did art a-level, art and design foundation for a year and a 3 yr degree in graphic design and you know what .... you don't need any qualifications at all, you just a good portfolio! i wish someone had told me that before i started because it'd have saved me alot of cash!
basically employers want experience more than they do qualifications - if you can prove you had a good eye for design, interesting ideas and the ability to produce them you can go straight into the job tomorrow.
if you want anymore advice on anything or have any questions on what sort of graphic design to go into my email is
[email protected] - would be glad to help ; )
