I thought ancient was really hard (esp. some of the Society questions and one of the Pericles ones) but i liked it like that....before you say anything, im not a masacist, but if it was easy and something i could have done without the lots of study i had to do i would have been really frustrated. Thats the thing about ancient, you learn (supposedly) so much content, and then they ask you one question, and you forget everything else you have been taught. At least in modern you learn stuff for more of a reason than "...it might be in your exam..."
I think any subject depends on a teacher - contrary to what youre told at the beginning of high school *HIgh pitched monty python voice* "Dont choose a subject coz of a teacher..."
There are good teachers and bad teachers - maybe some parrallel between that and good subjects and bad subjects?
