Yes! It should not be a secret that one of the best ways to prepare for your Level III exam is to practice past year’s essay exams.
I recommend that you do the exams from 2011 to 2015 and if you have more time then go back to years before that. However you should be careful to only spend time on those questions from past exams which are relevant for 2016. For the full relevancy table from past exams from 2006 to 2015, email me at info@ift.world.
