Creating the Examination Interface for Conducting Online Exams

I am looking for someone to create the examination interface for conducting online exams. The interface must be presented in a text-based format with the potential for additional animations and graphics. I have existing material and questions that need to be incorporated into the interface, which will specifically be made up of multiple choice questions. The successful freelancer must be able to create a robust and secure interface with timelines and milestones set out in advance. The interface must fulfil a range of functional requirements, including having the capacity for an unlimited number of users and an easy-to-use design. The examination interface should be accessible on any device and require no additional software for use.
