English CIE help!!

I got 58% for english lit and got told I got a C and an A* was 80% though Im pretty sure my school lied so i was wondering what your school said the grade boundaries are? I didnt revise at all english language for mocks but theres this guy on youtube called mr bruff who explains how to answer the english language questions pretty well so I'm watching his videos, then for english lit im just learning all my notes so I know ill have things to say and Ill read through a few of my better essays just to get a feel for how to answer the questions I guess. I hate english so much :'(

Thanks I'll check his videos then... well my school didnt really tell us the grade boundaries but apparently it was all graded excluding our coursework marks (which is 25%). In my french mock I got 2 B's but because of my controlled assessment I got an A...How are you with revision....I feel like ive just wasted this whole easter

literally same like apart from biology, chemistry and history i havent really revised any subjects properly I just procrastinate. Like i think im kind of a high A in most things because i somehow managed to revise properly for mocks and end of topic tests but if i dont get enough A*s my parents and school will kill me so lol im screwed
