Statement of Purpose is a sentence that you write, which states, in some detail, what you want to learn about in your research project. The statement guides you as you work so that you will read and take notes only on what's needed for your project

After you focus your topic, after some overview reading, write a sentence that says what you want to learn about. Don't worry if you're not totally sure, your Statement of Purpose may change 3 or 4 times before you're done. To write the sentence, first answer these questions for yourself as best as you can rute.
