Thank you for the short, concrete list of things that we can do, and for acknowledging that it’s complicated!

]]>Some more tips on writing an SOP:

– Your qualifications are already in your your CV. So, do not include numbers and dates and other details.

– Tell a story rather than having scattered facts. Try to weave all you want to say into a unified piece that has flow. If your paragraphs can be reordered freely, then it is a sign your essay lacks cohesion.

– Decide on an impression you want to make and adjust your language and choice of details accordingly. For instance, you may want to present yourself as an organized and hardworking person than, say, a smart/genius one. Deciding on the personality image you want to convey will really give your essay a soul!

– Include specific details not just about yourself, but also about the department. Let them know that you know them, and that they are not “just another school on your list.”

Good luck 🙂
