help for alevel english language

Hi, im a Y13 who takes english language alevel and im very stuck on how to improve. I just scrapped a B in winter mocks and im really wanting to improve my grades to an A. I feel like my content knowledge is good, i just feel so stuck. I take eduqas and the grade boundaries for a B were 77-93 and i got a 77 and my teacher wasnt that helpful with how to improve.
