How best should I prepare for my Cambridge (Oxford) interview for Economics?

The best way to prepare for your Oxbridge Economics interview is to be on top of all your A-level mathematics knowledge and to practise solving maths problems. I recommend trying the UKMT Senior papers for questions. Interviewers often ask questions on probability and statistics. Next, learn some basic first year micro and macroeconomics (I can help with that). This will really put you ahead of the competition in both the quality of your answers and the questions you ask the interviewer. For example, the pirates' game, a problem in game theory, has also been asked during interview. Finally, find an area of Economics you are passionate about and be aware of the most recent trends and the basic insight of the literature around it. I was very interested in income inequality and I had read Piketty's book "Capital in the 21st Century". I was prepared to spell out the findings of his book and delve into the basic mathematics of his model. Good luck!
