CFA institute mock exam

Hello,

I am a level 1 candidate gearing up for the december 2014 exam. I am in the final leg of my preparation and working on mock exams. I read somewhere that CFA institute provides us with one mock exam. However, in my candidate resources there are six mock assesments. Are there any old mocks included in these tests? Because there is no way for me to differentiate between these exams. Any help will be appreciated. Thanks.

Those 6 assessments are actually just two full exams, the latest one and one labelled "March ". It looks like six as they are each split into AM, PM and then a combination of AM and PM in one.

Thank you.
