I have taught physics at A-level since 1988, having taken the exam myself in 1983. In the past 25 years, the material on the syllabus has been diluted, with most of the mathematical requirements removed. We are left with a subject more akin to “physics studies” than “physics”.
The style of questions has changed so that there are continuous prompts. The questions frequently occupy more of the paper than the spaces for the answers. The marking has become more lenient and forgiving of terminological errors.
If you are in the UK and have some knowledge of this, I'd like to hear your opinion.
