Company Fe1 exam approach

He put a few rogue qs on last paper but I think you could answer 5 if u just based ur study on all the past papers. I’ve passed 6 first time by just basing study on past papers back until 2009 and am going to do the same for company but I’ll go back until 2014 given the 2014 Act. Is this sensible ? It’s hard to just try to guess what will come up. Despite the rogue 2/3 qs last year he does repeat questions really doesn’t he hmm

Thanks.
