I did A Level Biology back in the late 90s, and the one and only time we were given scalpels was to dissect lamb hearts. Definitely didn’t do anything like that in secondary school, but it was a particularly rough school, so scalpels would have been exceptionally riskyAre scalpels even common in schools in your experience?
I did biology through to A Level and never saw one, our coursework was on potatoes and osmosis! The closest we got to organs was a teacher inflating a pair of lungs with a straw. She got them from the butchers (we asked / were horrified) so a potential new recipe for Jack
But Jack went to a grammar school so I can well imagine they were allowed to wield scalpels at a younger age.
