I did General Studies A level. I didn't go to the lessons, and just learnt the different types of argument and knowledge on the morning before the exam. I got an A at the end of it all. I think it's because it's "easy" to get a good grade, it's viewed as a waste of time...I found that it doesn't really depend on how much general knowledge you have, but your ability to disect a statement and argue it (basically, waffle). I have to say yes I'm one of the people who see it as a waste of time, because it can intrude on other exams, especially on days when you find yourself having 6 hours of exams, with the energy drained early on because of General Studies! Another grade is another grade though!
