Took about 15 minutes, but got the bare minimum score needed to pass (second time in a row for that).

A LITTLE:
Amazon.com: CompTIA Strata - Green IT Certification Exam Preparation Course in a Book for Passing the CompTIA Strata - Green IT Exam - The How To Pass on Your First Try Certification Study Guide (9781742442464): William Manning: Books
USED ON DAY BEFORE AND OF:
MCSE, SCJP, CCNA, PMP, CompTIA, A+, Network+, OCP, Security+, Practice Test -uCertify
Most of the questions I did not even need to complete reading or read all of the choices (may have hurt me) because the first book and UCertify had me well prepared. I planned to gain this certification to be able to make better decisions for customers on purchasing, disposal and power usage once in the building. It went well over that in the first book listed and gave a complete overall picture of a leaner, greener, IT department. Even if you are not going for this easy cert, I'd recommend that book just to have the knowledge.
