Your statement of purpose should answer five basic questions:

1. What do you want to study? 

2. What questions within your field do you want to ask and answer? 

3. What experience do you have in this field? 

4. Why is this program a good fit?

5. What do you plan to do with your degree?

These questions, in this order, basically structure your statement. But don’t simply go through the list and answer each in turn. Just keep these in mind as you draft your statement of purpose and be sure each is addressed.
