Building your own custom exam is a feature available in the premium version of the app. The feature is called a Build Your Own Quiz and can be found on the Study tab, under the Quiz Modes section.
Once in the Build Your Own Quiz, there are multiple different filtering options to build an exam including a custom number of questions, specific subject areas, unanswered or incorrectly answered questions, and flagged questions. You can build an exam of all the questions you’ve gotten wrong, or focus in on a specific subject area you need more practice in.
The Build Your Own Quiz feature puts the power of creating an exam into your hands!
