I'm planning on purchasing my GMAT test prep books in the next day or two. I had a few quick questions.
1. I wanted to buy the Kaplan
2011 Premier book but saw that the 2012 edition will be available shortly (June 7, 2011). Should I purchase the 2011 edition, or preorder the 2012 edition?
2. I see that the Manhattan 4th edition guides match up with the first edition offical quant and verbal books, while the 4.1 match up with the second edition. Is there any way of ensuring that I'm purchasing the 4.1 Manhattan guides? If there isn't, should I buy the first edition official guides?
