Coming back from holiday on the day of Cambridge English Lit admissions exam?

I really doubt you will have time to get from an airport to a test centre in time unless it starts in the mid-late afternoon. Not even considering the fact after travelling (+/- jetlag) you will probably not be in a fit state to sit the exam.

I would suggest convincing your parent to reschedule said holiday. Perhaps during the actual school holidays...

What time do Cambridge do the entrance essay on the 22nd of November? Is it at the exact same time for everyone? I get back into England around 9am ish. I didn’t even realise my mum booked a holiday around this time.

it’s not at a test centre. it’s online, which is why i’m wondering. bc i could make it.

If you are serious about Cambridge, I would not risk it. Even if by good fortune you managed to get on-line in time for the exam, you would not be in the right state of mind. If you don't want to completely change your holiday plans, can't you travel 1 day before or after your mum to enable you to take the exam?

UPDATE - looks like it will be 9:30-11:00, so you definitely need to change your flight if you want to take it - https://www.christs.cam.ac.uk/current-applicants/remote-admissions-assessment
