The essential things to remember are:
- You must display a good grasp of written English - perfect spelling and grammar are critical
- Don't lie about what you have read - if you get asked about it, they will realise
- Do have an opinion, but don't say things you can't defend - it'll make you look thoughtless
- Read 'around the subject' and talk about. Why not read about Venezuelan politics or Chinese inflation? It'll show the tutors you're genuinely interested
- Structure the whole thing logically and make sure it flows - this is a proxy for what your essays will look like, so make it good
- Extra curricular activities are admirable, but ultimately, the tutors' main concern is that you will be a top student - try to link non academic achievements to how they have helped you develop personally - demonstrate that it will make you a more dedicated and hardworking student
- Express an understanding of how the disciplines impact and interrelate to each other: ultimately, PPE is about how society works, so try not to view the three disciplines as completely separate.
