Econ/PM/Deriv/Quant help!!! recommend, important, test, concepts, material

ap0258

I am retaking L2 this year and needed some help with these sections.  I found the CFA texts a little wordy/formula driven in their explanations and some of the EOC questions a bit convoluted.   I realize that most of these topics are not weighted heavily on the test individually, but that they have interrlated concepts that overlap and thus are pretty important.  Any 3rd party material/suggestions anyone would recommend to better grasp the concepts for these sections?  Thanks for your help!
