What do you mean "hold-over"? In NI we still say "first year" through "fifth year". Is that not done in Britain?

Typically no. In secondary school its just said as "Year 7", "Year 8" etc to 11, then Sixth Form.

I'm also from NI, our school officially used year 8 to year 14, but everyone knew both ways around and just switched between them.

Edit: I should clarify I'm currently in uni so this was fairly recent.
