You should research both the field and where you choose to apply. To research the field of Medicine, you should rely on both real-world experience and reading around the subject. Look at the GMC’s website and guidance, study the recent history of Medicine, and read any books that you find interesting about the subject or its specialties. Research interviews styles, typical questions, and how to approach these types of questions. Be confident on the difference between MMIs, structured panel interviews, or a wholly traditional interview.
Then research each university that you are applying to thoroughly – learn about the manner in which it teaches its course, and an overview of how its course is structured. Consider what sets the course apart from others. Investigate whether it offers dissection or prosection, whether it focuses on lectures, PBL, seminars or a combination thereof, when you will first be able to experience patient contact, where and when electives are offered, and whether you will have the chance to intercalate – and in what. Ideally you should attend open days as far as is possible, and try to speak to current or previous students of the university, in order to gain a real insight into where you will hopefully be studying.
Consider the ethos of each university – some are far more focused on science and producing future academics or ‘clinician-scientists’ whilst others focus more on those with great people skills who will focus on treating their patients holistically.
You should also research Medicine through your experience – volunteering, and seeking out placements at hospitals, GP surgeries and care homes. This form of research will bestow an actual understanding of the day-to-day life of a doctor or healthcare worker – and is invaluable when applying to university. Take the time to reflect as you learn, and to note what you learn down for future reference.
