I have the 2013 version and believe it or not, tis actually a good investment, not sure how you would use it, but it has actual questions from past exams. written differently of course.
Im doing the 2015 version right now, both the DD and MD. It is definitely tough but I am learning a ton. This combined with chads videos is a big help, especially if you learn best from practicing problems like I do.
Thanks for this post! Has anyone gone from 2014 to 2015 versions? $200 is a ton of money for me right now and I unfortunately purchased Destroyer in 2014 before I knew the test was changing for 2015. Certainly the newest version is the best, but is it significant enough of a difference to spend the money again?
