The exams take place in halls or rooms devoted to exams, filled with rows of students with tables and then invigilators, just like real exams. The size and who is in there depends on the University. For the larger subjects, they'll probably fill an entire large hall with just 1 subject.
With smaller subjects, they may use several smaller rooms, or they may put several subjects together in 1 exam hall. The exams will be completely created by the University. Normally, they're set by the lecturer(s) for that section of the course.
(This has caused me a lot of grief in my studies. I spent quite a while studying a certain aspect of evolutionary genetics from the questions on past exam papers, then found that the new lecturer who started last year disagrees with this aspect of genetics, so doesn't set questions on it).
The exam is set by the university. Each module you have an exam for is set by the lecturer you had for that particular module..so no two uni's will ever have the same exams because each uni follows different modules for each subject. -Yes the exam is set in an exam hall or sometimes a lecture room set under exam conditions.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
