2011 secret sauce vs 2012

Okay this might have already been discussed. I just did not find it.

I have the 2011 one from a friend who called it quits on CFA last year. I feel like I would have use for it because I am severly underprepared so reading it can help me gain a few cheap points here and there.

I dont want to pay for 2012 unless it make a big difference.


Thank you

im using it, just not for behavioral
