Hi
the revision books certainly have had any out-of-date questions removed, and as you say, they go back a full 10 years. However you may be over-estimating the scale of the problem here. My feeling is that 99% of questions are relevant, even when you go back to 2012. The topical issues questions are probably a bigger issue - and those questions are still in ASET and revision booklets, because the core reading background hasnt changed or been removed. It is just unlikely that a similar question would appear on that material in the current sittings.
I wasnt aware that they publish the ASET cross reference grid in SP2. It is only in ASET for SP5. However that shows all "relevant" questions, so its quite tricky to identify the odd one or two that are missing. If I were you I would simply assume that they are all relevant.
Another issue that I havent mentioned is that the style of the exams has changed since Covid when the exams went online/ open book. In past papers there were lot of pure memory/bookwork questions. These no longer appear in modern exams. All questions require you to apply the knowledge. In some older papers, memory questions were up to 30% of the marks, so thats quite a big change, and renders quite a few older questions redundant. Also the horrible long numerical performance attribution questions which were everybodies' nightmare, have not reappeared in the same way. (No reason why they could not ask those in an online exam, but they just havent so far).
Hope this helps.
