I think you should just keep trying with methods, in all honesty, that's one trial exam, and with the Multiple Choice - 1/22 seems surprisingly low, because there are always at least 5 questions in there which are easy or CAS questions. Are you sure you didn't do something like miss a line on the Answer Sheet, I've done that once
But alternatively, think about which subjects you're good at. Out of your 6 subjects, which are going to be in your bottom 2, if you're certain that methods is going to be in there, just ease back the effort a little, that's what I'm doing with Physics and Chem (going to be my bottom 2 for sure) - so I don't put much effort into them at all
It's up to your judgement though, do you think you're good at maths?

Also depends if you think Revolutions will end up being in your top 4
