[1] What is the most significant achievement you’ve ever accomplished so far? This could be a class project, a piece of artifact you built, or a research, and it doesn’t have to be related to our program.
[2] Is there any specific field you want to work on? Please be as specific as you can. Try to explain how your academic background prepares you to do research in this (these) field(s).
[3] If you have any previous research experiences, please explain them in terms of your roles in the projects, your own contributions, and most importantly the process of deriving the solutions/algorithms you developed, if any.
[4] In case your course grade is not particularly distinguished, why do you think you
still have what it takes to do graduate study in our department?
Last suggestion: the applicants are advised to take writing the study plan as serious as they possibly can. Think of it as doing the homework for getting into graduate schools. The more efforts you spent on it, the better chances you have to be admitted into topnotch graduate programs.
