it all depends on the person, if you like essays and dates etc do history, if you prefer whatever geography consists of then do that.
theres no such thing as an "easy" a level - if the questions are easy, the grade boundaries are incredibly high, thus making it not easy anymore, if the questions are hard, the grade boundaries are low. the exam boards dont make mistakes by making certain courses easier than others, its all based on the individual, so getting other people to rate it wont get you anywhere
