Hi everyone, I would like a bit of help regarding undertaking methods 1/2 in year 11

Ever since last year, I have strongly disliked mathematics. My teacher in year 10 was not great, and he made me look at a subject I had been an A and A+ student in in my past years as something I honestly despise now. Because of this, when I undertook advanced mathematics in year 10, I had almost failed the course (I got an A in the first test without studying at all, then proceeded to get only D's, E's and F's). I didn't study, as what the teacher was saying made no sense and I just gave up completely.
Going into year 11, methods 1/2 is a subject I'll undertake, but I'm really unsure of whether to keep it, do further maths or not do maths entirely. I'm primarily focused on doing law in uni, as I prefer English subjects. Although methods is not a prerequisite for law, I'm not sure what I want to do when I finish high school, and it would be nice to keep my options open. But, I'm worried that I won't be able to achieve even a 25/50 prerequisite for methods for other courses as when I even look at the questions, it almost seems like a different language to me.
My question is, since I have gone from being a great student in years 7,8 and 9 to absolutely terrible in year 10, should I try my best and work upwards of 1-2 hours a day to become better at Maths Methods, or is it not worth it seeing as though most questions don't even make sense/ are very difficult to me, and move to Further?
My current year 11 subjects for 2018 are: English Literature 1/2, Maths Methods 1/2, Global Politics 1/2, Psychology 1/2, Physics 1/2 and Legal Studies 3/4.
Sorry for the long question, thank you for reading
