I just finished with Devcon 2018 where I had a great time. One of the vendor's was Metasys Software and they made an app in the iPhone Apple Store that helps you prepare for the FileMaker 17 certification. I've used it in the past and it has been helpful in boning up on what you need to know to pass it. I can tell you that the questions are similar to the ones in the actual test (same difficulty, same style of questioning). Obviously first go over the FM 17 Certification Study Guide (https://www.filemaker.com/learning/certification/docs/fm17_certification_study_guide_en.pdf ). But for additional help at a fairly inexpensive price, I recommend FM Quizillaa.
