How to Brainstorm for Common App Prompt #3
If you think you want to respond to Prompt #3, first you’ll want to do some brainstorming. Be honest and open… you’re allowed to be imperfect.
- Was there a moment when you changed your mind about something big or small?

Strategies for Choosing and Developing Your Topic
- Start with Themes, Then Uncover Stories: This might sound counterintuitive, but I actually think it’s best to consider themes or values you want to communicate. If you want to show you’re resilient, try thinking of small stories in your life that showcase that theme/trait. I recommend taking a look at this values exercise by the College Essay Guy to help you get started.
- Free-Write or Make a List: Jot down childhood memories, meaningful conversations, or even inside jokes that capture something real. Often, your best topic is buried in something casual.
- Ask People Who Know You Well: What do they see as your defining traits or moments? Sometimes others see your story more clearly than you do. At the end of the day, it’s your essay, but getting input can be helpful. Just try to avoid getting too many opinions.
- Focus on the Details, Even When Brainstorming: The small specifics, the color of your grandmother’s sari, the first fish you caught with your uncle, will make your story stand out.

- Connect back to who you are today: How does this background, identity, interest, or talent continue to shape your choices, values, or goals?
