I found English quite easy whereas a lot of my class didn't even know what a noun was!! (true story, same with verbs, adverbs, synonyms, conjunctions and acronyms!). I guess it depends on how your mind interprets and can handle data. It's completely subjective.
For instance, I understand that Media and Film Studies don't appear to be very difficult at all to those who haven't experienced them, but as with most subjects it can be very difficult when it comes to interpeting the texts and offering explanations for various things (that frankly the producers probably weren't aware of :P). If you don't have imagination, knowledge of psychology (I took that too which helped) and strong opinions about things like society, politics, environmental issues and other stuff relating to the world and humans then you'll find subjects like that exceedingly difficult as you won't have an informed viewpoint. Surely working rapidly (in exams) to provide an insight and a hypothesis for various unknown narratives can't be easier than simply remembering a load of facts and figures?
And is perhaps on a par with English Language and it's interpretation of characters, setting, dialogue, metaphors etc?
Though I must admit Chemistry, Biology and Physics sound like complete destroyers of the brain :P I guess fact-based and interpretation-based subjects are tailored to more deductive and inductive personalities, respectively? I feel it to be quite unjust that those of the latter face dissapproval just because they think differently.
Personally I prefer it when my subjects aren't set in stone, though I did love science and algebra at school
Did you do any MFLs at A level? Everyone seems to put them down without ever having done one at A level. The majority seem to be people doing mainly sciences who are shooting them down whilst never having done a language past GCSE.
To learn a language (thousands and thousands of words etc.) is a lot more different from learning things from a book. It requires a different mentality - from my past experience at least!
I'm a native French speaker and, even though I understand everything, I find it hard to 'play to the exam board' to get marks. I also think the essays at the end (exclusive to my exam board) are really stupid. Obviously the tenses, spelling and/or grammar which stump so many people aren't really an issue for me.
I'm joking of course, I do art myself. I found chemistry to be the toughest, the amount of content you have to learn is imense. If you fall behind even slightly it hits you hard.
Chemistry. There's just so much you need to learn and then, even when you've learnt it if you can't apply that knowledge in unfamiliar contexts then the exams are incredibly tricky!
