MyWorldAbroad is constantly trying to streamline the registration process to make it quicker for students.
Schools using the Quick Access System (QAS) now have access to the Quick Registration System, which prompts students to go through a short registration process when they star an article or resource, or when they access the quizzes. See an example here. And please view more details on MWA registration systems here.
This means that students are able to access site content, and then prompted to register when they engage further with the content.
