Difference in curriculum between Sept. and Mar. 2011 exams

So this is kind of late but I was only able to get a hold of the March 2011 Schweser material. Is there a big difference between March and September or do you guys think I’ll be ok? I have a hard time believing they’d change it up so much that kids who didn’t pass in March would have to fork over another $500 for brand new materials, but then again this is a money making machine so you ne’er know. Any help on this would be greatly appreciated!

no changes bro from march to sept of 2011. It is changing for march 12
