English majors can mainly study English language and literature, foreign linguistics and applied linguistics (English teaching belongs to one of the two directions). Because your undergraduate course is English, the postgraduate entrance examination does not involve cross-majors. As long as you have a reliable language foundation (including foreign languages) and a solid and targeted review, the postgraduate entrance examination should be no problem.
As for the school you choose to apply for, it depends on your own strength and the competition for postgraduate entrance examination. My suggestion is to apply for 2 1 1 or above, which is good for your employment. I have your experience, too. Graduate students are about to graduate.
Wish you success!
