should i drop to ordinary level maths now or after mocks?

im in sixth year currently and wondering wether i should drop to ordinary now or after mocks? my teachers are giving me mixed feedback so its a bit confusing. im averaging a h6/h7 at the moment, but the course im going for needs a minimum h6. i dont really need higher maths as im averaging h1s and h2s in all my other subjects and maths has never counted in my points overall. i do feel like i can improve with an extra push in maths as i never give it any attention, due to all my other subjects being so time consuming. but that could take from my other subjects as maths is so study-heavy. you just never know how it will go on the day and higher maths could save me?? any advice would help!!!
