Worked on the OffLearn repository to establish a reusable UI scaffold supporting assessment flows such as pre-tests, test results, and quizzes. Leveraged Java, JavaFX, and FXML to create modular, testable UI components, focusing on both learner engagement and instructor insights. Developed FXML templates and Java classes to scaffold pre-test and test result interfaces, enhancing the pre-test UI with detailed subject and instructor information and a clear call to action. Implemented quiz details and results views, including student scores and performance statistics, while refactoring package structures for maintainability. Prioritized robust UI foundations, addressing integration issues and preparing for future feature delivery.
