Also my sister is an alumni at UC Berkeley if that counts. Not sure what to write for my personal statement yet, but I’ve had a tough childhood (abuse, mental illness) but I’m not sure if I’ll mention that in my application bc that did affect my grades but I’m not sure if colleges would want to read anything like that. It’s sorta risky to write about.
