Hello there, I'm sorry to hear about your issues with the CAS system and meeting deadlines. Unfortunately as the process changes regularly (it usually gets altered from intake to intake) it is unlikely you could receive an extension unless you have unique extenuating circumstances. Please remain patient with the team will be working incredibly hard right now around deadlines and results day. For any in depth queries/requests please contact either the CAS Team through the chat function on CAS Shield, or The International Enquiry Team on 024 7765 2152 or the Live Chat https://www.coventry.ac.uk/livechat/ as these are the official communication methods used by the university they are the best and most direct routes on offer to help you out. Please ensure you have all the documents required and up to date on the form and when contacting the team.
Hope this helps and best of luck with your application Dan - Student Ambassador
