They are pretty much identical to the questions set in lectures; it is basically, 1 lecture= 1 essay topic. All questions are in essay format, roughly 45 minutes suggested time for a question.
Do about 3-4 arguments in the essay; they prefer you to say a good and in-depth argument rather than saying lots of things. Don't show off and demonstrate how much you know, just argue very hard, the knowledge will make itself known if you argue well.
You don't need to read that much far beyond the reading list; they don't want you at 1st year stage to do wider reading (you might read the wrong thing, or not properly understand certain papers). The questions are straightforward and you should do well if you have thought for yourself, went to the lectures and did lots of reading.
Second year, however, is a nightmare and you are supposed to feel completely lost (and it always involves Two Dogmas of Empiricism!!!)
