In my believe, the content is not bad. Only becoming easier for people to comphrehend if they willing to put the work in.. take it 30/40 years ago, there has been much changes in advances which make it easier for students to get the resources and learn, like through the internet; youtube etc. Also the content takes in the fact that other people sturggle too, so they have taken that into account.
But what hasn't changed, is the exam experience, the struggle and pressure which students have on their shoulders to do well and that their whole future is based on this phase of life. I know, I felt the same at GCSE and now when I help my brothers out, and see the content, it's like,... what was the fuss. And I realised that no matter how easy or hard the content was,, it was the situation which made it hard.
Got luck to all who are doing exams.
