The problem DExa solves

Institutions or test-conducting agencies, regardless of their size or operational mode (public or private), can utilize this application to create and conduct computer-based exams. Typical problems such as question paper leakage, response tampering, and other disputes can be tracked and proven through DExa's web3 solution. The key point is that it maintains the familiar exam process and user interface/user experience while leveraging the power of web3 technology behind the scenes.

Challenges we ran into

Having file in IPFS is not secure as anyone can access it through link, we added a layer of RBAC to fine grain the access.
For scalability we used APTOS. Student responses will not direclty enter the chain, it will be built as a tree and then added to chain.
