CAS Shield will be auto-populated with information about the candidate and the candidate's programme that he/she provided at the time of application and he/she has to check this for accuracy. The information provided by you must be correct, otherwise, your visa may be refused.
How to Check Your CAS Shield Status?

What is Confirmation of Acceptance of Studies?
