So how do I know what universities want? Start by reading about the university, the course you want to study and the "entry profiles" as these will give you information about the type of student the university is looking for. Universities also want the truth so do not lie about your abilities and they want your writing so do not ask someone to write the personal statement for you. Some areas to cover include why you want to study this subject, what your future career plans are, what you do in your free time, what skills you have (academic and non_academic), what's interesting and/ or different about you.
How to write a medical school personal statement: Motive _ Third is having a compelling motive. It's the underpinning of the whole essay. Unless you speak to a compelling motive, the default result from the reader's point of view is this student is writing a general medical school essay, but doesn't really know why. You've got to be willing to flaunt the motivation and be really willing to shout at the top of your lungs standing on a chair in the middle of a crowded auditorium. Be THAT committed to what you have to say. All of this sounds incredibly unrealistic and incredibly overdone, but once you put these concepts down on paper, the very act of reading mutes so much of the impact of language, that you've got to be willing to trust that you can be very committed and very over the top in how you articulate, and it will still carry off.
