2011 vs. 2013?

Greetings,

I have taken the Becker FastPass this summer and did not get good results. I retook REG at the beginning of January with Becker again and did not pass (again) with a 68, one less than my original score.

I will begin to study again in April after busy season and have bought the NINJA notes. I plan on using my becker videos and MCQs but will rely primarily on NINJA notes and Wiley test bank. I currently have a license for the 2011 version of Wiley but I am wondering if I should upgrade to the 2013 version instead. At this point I really don’t want to fork up the $200 for the newest version. Can anyone attest to the differences between each year? I am afraid that if I don’t get the newest version I am going to miss something important.

As mentioned, I still have access to my Becker software until November but I feel like I know the answers to 90% of the questions without even finishing reading the question.
