Hey, I received an offer for Cambridge Economics this year (taking Economics, Maths, Further Maths and an EPQ in Year 13) so I might be able to offer some advice
I'm going to do a full Cambridge Demystified chapter after results day if I get the grades which I need, but I'm happy to answer any questions you have now!
One of the key things Cambridge look at is supercurriculars (activities outside of school that are related to your subject). These can include:
- Essay competitions (RES, Marshall Society, John Locke, etc)
- MOOCs (Massive open online courses on websites like FutureLearn and Coursera)
- Wider reading (I would recommend you try and find a niche that you can focus on when writing your personal statement in year 13 - most people will have read books like Freakonomics and The Undercover Economist so I would recommend these as intro material but wider reading around the subject to find a specific area you're passionate about can really make your personal statement stand out)
- Internships/work experience (This isn't at all essential for economics, but if you do want to do any work experience, thinktanks like the IEA usually run sixth form programmes in the summer of Year 12)
- Public lectures (RES, Marshall Lecture, most universities run public lectures that you could go to - they are often online and available to watch after so don't worry if you're not in a position to be travelling around the country to watch lectures)
When choosing a college, I don't think that you need to make a final decision now (I changed my mind in the middle of year 12) but it could be good to consider the factors that you would prioritise when choosing a college. Lectures are taught at the university level, but supervisions (small teaching sessions with fellows) are organised by your college. Whilst you will cover the same content, if there is a specific area of economics you are interested in you could look to see which college has fellows that specialise in that area of research. I personally looked more at the college atmosphere when applying (factors like location, size, the vibe I got from it at the open days, accommodation, food, etc) but it will depend on what you are looking for in a college.
In terms of the summer of Year 11, I spent it preparing for A-Levels and reading around the subject of economics. Most of the supercurricular opportunities like essay competitions won't open until next spring/summer so for now I would suggest reading things that you enjoy and developing your passion for the subject because that is what will be looked at in the interview.
Best of luck for year 12 and 13!! Feel free to reply if you have any questions
(Also, please don't listen if people say it's too early to think about uni - everyone starts at different times and preparing now is definitely not a bad thing
)
