They are on the school website!!!

Distances have come right down and the mean score has gone up to 180 this year.

I can also see that cut-off score has increased from 236 to 242 - does that mean that overall trend for other schools too

No, because that is the score taken for their technology exam which no other school does.

The highest score for band A entry has gone down slightly and the lowest scores in all band have gone up slightly from 2017, which are the only comparisons that you could potentially make with scores for other schools, but I don't really think it tells you anything at this stage.
