PSM I Exam Prep
I am due to take my PSM I exam. I have used a variety of learning resources. However, I DO NOT recommend either 'testahoy' (http://www.testsahoy.com/it-certification/agile-and-scrum/mock-tests-fo…-(psm)) or 'the scrum master' (https://www.thescrummaster.co.uk/) for your revision. Both are God awful resources with incorrect answers to numerous questions. Stick with scrum.org and associated material. Seriously.
Aside from the resources listed on the PSM 1 prep page, what other resources have you found the most useful?
