How to defer uni?Watch
You will need to contact the university and ask them if you can defer your entry.
Wondering how to defer uni for a year if I decide to in august, I highly doubt i could deal with online classes and would much prefer to be a fresher the following year.
Deferring just means ringing or emailing your firm choice and asking. They might refuse (unlikely for most universities) in which case you can reapply to 5 choices for 2021 entry in September instead.
