CFAI Previous Year Mocks (2012-2016) Vs Schweser Practice Exams

Hey Guys, Keeping in mind the little amount of time left. Can someone please suggest me what to do regarding the practice exams. Should I focus on the CFAI Previous Year Mocks or should I go for Schweser Practice Exams. I am done with the Topic Tests.

I always believe that previous year mocks is never a good idea, since curriculum changes (not to mention that the change from 2016 to 2017 is a significant one)
