Seriously, how can an English exam be easy? The questions are always going to ask for an exploration of themes or characters, and hence the responses can be as sophisticated as you like. It's not a maths exam where questions can be easy because there's only one possible response; English tests your ability to construct an argument, to craft prose and to explore ideas. The only way in which an exam can be seen to be easy is if there are topics which are broad and typical enough to be known to the very bottom end students, and can hence create very simplistic essays. I don't really think you can have a hard or easy language analysis: if it's straightforward, you've got to somehow pick up nuances, and if it's complicated, you've got to achieve some sort of clarity in your writing.
