Studying for the Analytics Business Practitioner Cert

I'm hoping folks can point me to some free or cheap resources to prep for the Analytics Business Practitioner Certification.

• A great book (most I'm seeing on Amazon are old and for Sitecatalyst)
• Video tutorials
• udemy,  lynda, etc

Looking for folks that have used something other than the formal/expensive Adobe training and have gotten certified.

We have around 10 folks here that are interested in getting certified.  Adobe's eLearning classes were $3k and there is no way I would be able to get budget for all of them.  I'm looking for cheaper alternatives for people willing to put in the effort.

Thanks
