Computer science or economics would be your best get imo, but if you wanted to go more towards the humanities side and are enjoying English lit then what about Law?
With computer science or economics, you could literally do anything and say for some reason your a level grades do slip up as long as you get a 2:1 this wouldn't be a problem as they care more about the degree and experience. If you do pursue law however, your a levels are very important and you need at least AAB but this doesn't seem like a problem with your ability anyway! Do you enjoy extra reading and keeping up to date with current affairs?
