Test-Taking Interface Specifications

As a user, I want to have a seamless and secure experience while taking tests on a web3-enabled Scantron testing system across desktop, mobile, and tablet platforms, ensuring the integrity and verifiability of the test-taking process.

Acceptance Criteria

• The interface adjusts responsively to desktop, mobile, and tablet screen sizes without loss of functionality or design integrity.
• Users can authenticate using web3 wallets like MetaMask to sign in securely.
• The test interface provides clear and concise instructions for test-taking.
• Users can select answers using a point-and-click interface on desktops or touch interface on mobile/tablet.
• The system records answers on the blockchain for transparency and immutability.
• Users can review and change their answers before submission.
• The system confirms test submission with a transaction receipt.
• Users receive real-time notifications upon successful submission or any errors during the process.
