Essays often require a level of vulnerability. However, only be as vulnerable as you are comfortable. You do not write about any trauma if you have not worked through it and/or are not comfortable.
Answer the WHOLE prompt. Many prompts ask multiple questions but sure to address each question in your response.
Be creative. The essay is a chance for you to stand out from other applications. Be sure to let your own unique voice to shine through in your essay. Dig deep!
Do not be afraid to restart. Essays require many, many drafts and edits. Perhaps it will be helpful for you to brainstorm and write a few responses to one prompt, re-read them, and choose the one that speaks to you most.
Avoid repeating what is already shared on other parts of your application. For example, do NOT use the essay as a chance to list all your academic and extracurricular achievements. This is your chance to share new information about yourself with them.
What are you passionate about? How do you think about the world? What hardships have you faced and overcame?
This is really the only part of your application where admission counselors get to hear from you in your own voice! Take advantage of this!
