Yeah further is a simpler subject - i probably put 1/8th the time i spent into methods into further and scored similarly in both. I found further a breeze compared to methods, however, I still spent a good amount of time in it. I spent about a week of the summer holidays going through the core topic (statistics) and then spent most classes effectively, and then probably a night before a sac studying for it. Which is considerably less than what I'd spend for methods. The questions themselves were simple, and there's literally a small cap they can place on the cycle of questions (theres only so many questions they can ask, unlike methods where they can really test your understanding of the subject)
The subject itself can get quite boring because of its simplicity, and I enjoyed studying methods more for its complexity. However, having done those subjects last year,
I can say that I appreciate further much more because it's the most applicable to real life. I didn't really recognise how important this was until after year twelve, where I've spent a whole year learning the study design and not a subject.
Just a different perspective you might want to consider
tldr yes its easy if you do the work, + good shit to know for lyf
