Not sure if this is in the right place but eh

I did two 3/4 subjects this year and so did not spend ANY time on methods 1/2. Needless to say, I did horrible! I now have a major issue with methods and freak out in tests etc. We did 2 weeks of year 12's and I tried really hard to do an exercise a day (which is a lot for me!). It wasn't a hard chapter or anything and I did the work, but I still bombed out in a surprise test.
Seeing as I'm only doing 4 easyish subjects this year, not including methods haha (eng, lit, business and methods)
Maybe I should take Further as a 7th subject, do the course in the holidays and score better in it than methods.
I need a 98.25+ to get into the course I want, and I'm definitely not looking forward to destroying myself trying to do well in methods.
So here are my options.
1) Do further and methods - score well in further e.g. 40+ (which I think I'm capable of) and get a 25+ in methods (prereq)
2) Don't do methods and just further and just do a bridging course if I decide that arts/law is not for me and I want to do commerce, science or anything else instead (no idea how bridging courses work etc, so could be a bit risky)
3) Don't do further and fight it out with methods
Any advice?
I've never wanted to do methods, but I realise that a lot of courses require it and I'm not entirely sure which courses I'd actually be fully interested in, because I could end up hating doing law etc.
