I guess you may have input a wrong name; it should be MBA in Management. To write a qualified PS, you first need to self-examine yourself in depth and comprehensively, including your personal growth, academic history, and social activities. You should define your career goal in both short and long term; then tell others why you get interesting in this field, what you have prepared for the development in this field, including your management potential, maturity, personalities....Finally, state what you can bring to the school you apply. You should make you qualify for the admision creterio as well as fit for the school's culture. For good writing examples, you can find a lot in this forum. Good luck! |
