But all of that aside, another important thing you should be doing now is building a bit of experience. Grab Unity or Unreal engine (whichever appeals to you most), youtube or find a tutorial for it and work through it and make the games they make in their tutorial. Then start building your own games.
Thanks for the reply! I can't take any a kevels cause the entry requirements for an A level is a grade 6 and I got a 5. Can you give me more info about unity or unreal engine, like whats the best if you want to become a game developer.
