Old CFA mock exams - Which are still relevant?

Does anyone know which questions from the 2007 through 2013 mock exams are no longer relevant due to the material changing?

start from 2006 , that should be good . before 2006 is not that relevant.

I didn’t do anything prior to 2009/10… Those formats/content felt different to me. Re-doing example boxes and EOCs seemed like a better use of time than doing really old exams

The helpful part of doing full mock exams is that it helps build the endurance needed on exam day and is a better simulation of the actual exam. Do you think it’s better to do 2014 Schweser mock exams instead of the 2008-2009 CFA?

I believe the CFAI recommends reviewing the previous 3 years of exams.
