Here's my two cents on the difference between English and Literature.
In English, you have three distinctly types of essays: Text analysis, expository and language analysis.
In Lit, these three types are kind of combined into one. You have three passages in the exam. First you analyse the language (Language Analysis), then you pull back and analyse the text as a whole, complete with themes/characters/etc (Text Analysis). THEN, you pull back even further and give a kind of expository overview of how the text relates to the real world (Expository).
I know it sounds complicated, but Literature essays give you soooo much more freedom to express your ideas, and particularly, your style of writing. I know a couple of friends who are struggling to get the confidence in their "voice" through in their English essays, and therefore struggling to get the best marks they could have achieved.
Having said that, though, I've had some sort of grudge against standard English because of past experience with narrow-minded teachers.
