Задача

However, many awarding bodies have their centers distributed worldwide and, at some point, they want also to provide a phone-based delivery, thus ensuring their ability to deliver exams to candidates no matter of center infrastructure or location.

This requires the platform to be extended with a new application. It should be integrated with already existing product modules varying widely from test content creation to assessing students’ responses, and there should not be any significant changes in the core assessment platform.
