CAIA stackable credential - CFA Charterholder POV please

I am wondering if anyone who took the level II CAIA exam under the stackable credential program can give insight into their experience. Was the material similar to the CFA curriculum in Alts/Quantitative Analysis/Ethics? Your opinion on exam difficulty? Hours studied? General advice?

I am thinking of registering for the September exam and want to hear from other Charterholders before I do. Thanks in advance for any info!

Yes, same here It looks like a nice add-on to the CFA. Thanks.
