HELP - gcse English lit, how to improve??

I’m currently on a 6 and usually capped at 20/30 on essays.
I do AQA - Macbeth, Christmas Carol, AIC and then power and conflict anthology
I understand how to revise its more what I need to write to get into the higher levels because the mark schemes are not very clear.
If anyone has any resources to help that would be really helpful
