GIPS: Does Schweser suffice or is this a text-must read?

Haven’t gotten to SS18 yet (yikes, feels like I’m terribly behind), but for those who are primarily relying on Schweser, does Schweser do a fairly good job w/ GIPS or is this a case where you REALLY, REALLY should read the text? Feels like I’m on a time crunch. Cheers in advance for your $0.02.

I studied from Schweser and went straight to the CFAI EOC and could solve most with the exception of the tax calculation problem. IMO that is out of the covergae of the LOS’s.

I’d say must read. It’s practically guaranteed to be on the exam, and there are so many minute rules. I use it in my job and have read it many times, and still keep getting railed on minutae on the practice exams.

Thanks heer & ng30!
