I reckon it's all relative. After (most of us) have finished GCSEs, we look back and see that the exams weren't as frightening as we expected, and the coursework wasn't too demanding (except when you had 11 pieces on the go at the same time) and generally it all came together at the end. However, I bet at the start of year 10, most of us saw the amount of stuff that we had to learn as a pretty daunting task, although at that point the urgency and stress wasn't apparent. Wind back to year 7, and GCSEs seemed like the scariest things in the world. I bet most of us here got wound up a little by those. Year 9 SATS, the first in proper exam halls (well for us at least) sure seemed challenging at the time. It's all relative. As we move on, some may get jobs, and maybe even move out for the first time. What a leap and a challenge. Some may do A levels where you finally begin to start speciallising, and have to learn in depth about things. Challenging also as the work committment piles up. Moving on to uni is another great challenge. Living on your own, having to get to lectures in a less structured environment, being completely overworked, and then spending months revising for individual papers. Getting a job is another great challenge. Then follows advancing in the carreer ladder, finding a home, starting a family, fullfilling what you want from life, retirement. It's one challenge after another. As we get older we become wiser, and looking back we realise what a good deal we had back then when the work was easy (although it didn't seem so at the time). GCSEs are taken by pupils of all abilities, and while to the brightest, most organized and hardest working they can become easy, they are certainly still a challenge. Taking 9-11+ of them means that you have to broaden your knowledge and use a wide range of skills.
