This Android application, "Elementary School Question Bank," is a new tool designed for fourth and fifth-grade students. It offers a new system with thousands of questions and automatic correction, eliminating the need for manual question printing. The app features a variety of question types, allowing users to create their own tests by selecting question types and quantities.

Users can specify the percentage of repeated and new questions, enabling the app to generate random tests based on the set criteria. Tests can be taken immediately or saved for later, with automatic grading upon completion. Incorrect answers are highlighted for review and correction, empowering students to learn from their mistakes independently.
