The University of Exeter typically aims to respond to MSc applications within 20 days of receiving a complete application with all required documents. Since it's only been a week, it might still be within the normal timeframe. However, given the urgency you mentioned, it’s understandable that you’re eager for a response.
It might help to follow up with a polite email to the admissions office, reiterating the urgency and your scholarship applications. Sometimes a gentle nudge can speed things up.
Good luck with your applications and scholarships
