Dude don't worry about these level things, I got like a level 6 in English and I was one of the best in my class for GCSE in top set (got B's/A's - yes my school sucks at English it seems as hardly anyone got A*'s). You will do fine in GCSEs don't worry. You have 2 years to study for it, I know you want a predicted grade, but only you know your capabilities and a lot can change from now til you take your exams. But from what you got you seem above average yes, apart from possibly English which is average I'd say.
