anyone studying both core readings and schweser

I was wondering , especially for the readings of market risk , concepts like coupulas , non elliptical distn etc deserves a deeper reading than schweser ,but i have no much time on hands so i am sticking with schweser and wikipedia

It would not be wise to be reading from core material at this point. Focus on the macro-level concepts and do questions. For copulas, know what they are, their properties and what they are used for. No need to dwell on confounding material.
