stuck on the same grades eduqas a level RS.

i keep getting scores from around the high c low b areas in every test, generally around the 27 to 33 out of 50 literally every test, even though in some tests im almost very confident whereas other tests im not as confident im getting around the same scores. example, i got a question that once said "explain the sources of sharia" according to eduqas there are 4 sources i went through all of them and even gave examples of rulings that come from each source and went into detail yet only got 14 out of 20. and in ao2 it was whether sharia is divine or more human, i gave clear arguments with scholarly evidences and some counters but i cant seem to get higher marks. not just this but my teacher writes model answers on the board and they appear so basic and in my head im thinking that if i was to write that model answer word for word i wouldnt get the highest marks. Does anyone have any advice? studied islam in eduqas a level? model answers?
