Study Mate is a Power Platform solution I built and use to help me study for exams. It allows me to create flashcards and vie them in a canvas app while on the move.
Visit the Study Mate GitHub page to download the solutions and sample data – https://github.com/PaddyFreefall/studymate
You will need the Dynamics 365 data migration utility in order to install the sample data. Instructions to download this are available here – https://docs.microsoft.com/en-us/dynamics365/customerengagement/on-premises/developer/download-tools-nuget.
