At home we had an old O-level mathematics (old British system, compulsory at age 16) book lying around. Two things stuck out: A massive amount of material: lots of calculus, matrices, complex numbers, group theory, ... And almost all of it explained extremely badly

The O-level physics book we had lying around was even more brutal, far more physics than I ever learned in my life. Pretty sure the total content of my physics A-level (optional, age 18) would have been squashed into just a few pages of that

To be fair, I took my exams at the low point in difficulty (towards the end of the Blair administration), after that they got harder again My physics A-level involved zero calculus. There's really very little physics you can do without any calculus at all

Replying to @_julesh_
I thought a bit about "physics without calculus" recently and one important idea that came to mind was dimensional analysis (though this isn't emphasized nearly as much as it should be). After that I could only come up with a few toy examples which mostly consisted of ...

solving for steady states on graphs. E.g. computing forces in simple statics problems consisting of rigid free-bodies treated as points or computing currents / voltages in resistor networks. (Of course, these are certainly enriched with knowledge of calculus).
