Cambridge TMUA Test Date 2023 - Can't Attend

I am from Scotland, and our holidays differ from England. I am unable to attend the test date of 18th October 2023 for the TMUA as I am on a long-haul international flight that I cannot reschedule. I have no idea what to do next, as this wasn't even a possibility before. Does this mean I just can't apply?

I suppose I could apply for Maths as the STEP is in June, or apply for Oxford and take the MAT, but my dream is Cambridge for CompSci.

have you figured out a solution as i have a similar issue

ah sorry to hear it! I did manage to cancel the flights eventually but my parents had to pay extra. i’m taking it the morning of the flight. my other option would be to take a gap year & do industry experience & then reapply

thanks
