Kennedys TC 2025 & SQE

See how the email says we have a week - I received the invite last Wednesday (28th), does that mean I can do it this upcoming Wednesday (6th)? or would that be considered the 8th day, confused
 
Does anyone know if you can defer a TC offer to finish studying PGDL? I’ve got a VI for kennedys but I’ve swapped to part time PGDL so I graduate 2026 now instead - do you think they’ll be able to defer me?
On the one hand, if you receive an offer, you are a good fit, so it shouldn't make a difference. On the other hand, they might base their offers each year on the quality of candidates.
