Reading 48 - Necessary to use CFAI or can use Schwesser?

CFA Level I
#1

I’ve been sticking to CFAI 100% and was wondering if reading 48 can be substituted. THere arent even CFAI questions in the book for this reading! Will Schwesser be ok?

#2

Is it really much shorter in Shweser? Reason I ask is that I was thinking of using just Schweser for the whole Corp Finance/PM reading, but then I saw that it is about the same amount of pages as CFAI texts, so what is the point?

#3

I just read it in the CFAI texts…snooze central. not even a single practice problem in the book. I doubt there will be a question on the exam from this reading.
