I would like to ask if past papers prior 2012 can be still used for revisions, I read somewhere that around 2012 t exam format has changed so I am not sure if papers prior to that can be of any use for current students
The format changed a little so that Q1is now 50 then you do 2 x 25. Before that Q1 +Q2 = 60 then you did 2 x 20.
However, the examiner didn’t change then (the current one started in Dec 2010, if I remember right) so even though the sizes of the questions might be a little different the style of the questions and the examiner’s interested didn’t change. It is still worth looking at older papers.
