About The Project

W3 Exam project aims to address the need for a solution that can mitigate the reliance on consistent high-speed internet connections for online examinations. By leveraging cryptographic algorithms and secure distribution methods, the project seeks to enable students to access exam materials in advance, minimising the impact of slow internet speeds. This approach offers an alternative for students in regions with limited connectivity, allowing them to participate in online exams more easily and reducing the likelihood of opting out due to connectivity issues.
