I am taking the NCLEX in the near future. I graduate in two weeks and want to start reviewing now. Should I buy the Kaplan 2011-2012 edition or the 2012-2013 edition? I know they are changing the exam in April 2013. I am thinking the 2011-2012 edition since it is (or should be) relevant to the version of the NCLEX I am taking. Any advice is appreciated. Thank you!
