With all due respect, Further is not "easier" and saying that is really an insult to those who choose to do Further. You need to understand that different maths subjects cater to different people and their circumstances/aspirations. Those who view Further as 'easy' probably have done (or are doing) one of Methods or Specialist Maths. Clearly they are going to view Further as an easier alternative, because Further is not directed at them.
wut
why do you say it's not easier?
I was in yr 11 completing 1/2 methods and spec and was able to help my yr 12 brother with further (he scored in the 40's) (2015 so old study design) mostly through mathematical common sense and/or revision of yr 7 -9 concepts although you need to read the exam questions carefully. Haven't really kept up with the changes

so might not be able to do so for the current one. Although IIRC it's just a rearrangement of topics.
Honestly most further students (even those who aren't particularly strong at maths) say it's easy.
Mainly students choose further because they feel methods is too hard but they still want to do some maths, usually not for the real world applications. (because if methods was accessible they would do that instead LOL) So they aren't really doing it for the applications.
