Why Trinity Hall?

As a Psychological and Behavioural Sciences (PBS) student at Trinity Hall, you’ll be supported by a Director of Studies with a background in neuroscience who specialises in the psychology of political behaviour and has been recognised by the University of Cambridge for teaching excellence.

Alongside academic work, a growing Psychology Society and links with the Natural Sciences community create opportunities for you to engage with current research and connect with students who share your interests.

In terms of just prepping for the interview, my psychology teacher printed out some sample questions, so I went through them with a friend and I was like, can you try and pick holes in my arguments, just get me used to talking through these things.
