I'm appearing for step 1 in May/ June next year. Which year's Kaplan notes should I buy? 2013-2014 or the next edition?

For now I believe they only have the 2013/2014 (maroon cover) edition. Not sure if they release a new set every year or not (there wasn't that much of a difference from the previous blue cover 2011 edition anyway).

I actually have an extra set of the seven Kaplan notes/books for 2013/2014; set is brand new and for sale on Amazon. Message me if you're interested. Books are printed in the US.
