Yes, but it also depended on the actual aylabus you did.
As someone has already said, O Levels were for the top 20%, CSE were supposed to be more practical and for the next 30%.
It was expected that half of students would leave school at 16 with no qualifications.
So some subjects you could only do CSE eg typing (thinking back to my school days an age ago) which fitted with being more practical.
But CSEs were offered in academic subjects too. I struggled with Chemistry so I did O Level and I also did CSE.

I would say most of the computer science curriculum is identical to what it was in the 1980s. The only big difference is knowing about the internet and online safety.
Programming - the languages are more advanced but the principles are the same.
Different types of networks are the same.
Software mediums have changed.
But the binary, bytes, nybles / nibbles, input and output lots is the same.
