For Physics:
Avoid the questions on Sunspots (up to 2010)
For English:
Basically anything pre 2009 is probably not that useful
Anything 2009-2014 is Belonging focused for AoS: I guess you can treat every Belonging you see as 'Discovery' but it may not work for some questions because the chosen texts/articles simply have nothing to do with Belonging. The Module A,B,C questions you need to select whether the questions asked each year are text-specific (i.e. if the question is targeting a theme in the text), if they aren't (eg. the question is about comparative study and context as a whole) then you can surely attempt it. But if they are specific and your text is a 'new' text (i.e. not Hamlet) then most of the questions will be useful, if your text is recycled (eg. Hamlet) then you should have no problem trying those questions
2015-2016: If you do try these papers, yes the questions are relevant but they probably wouldn't get asked again so keep that in mind
