I'm dyslexic/neurodiverse and am unsure how to write about that in my personal statement?

Hey, me too! And it's never stopped me from being a high academic achieve and it won't stop you. Our neurodiversity is what makes us unique and interesting. Overcoming our difficulties in learning, which you have done otherwise you wouldn't be sat here today, is a great achievement and that's a fantastic success to brag about in your statement. As we are neurodiverse, we have had to creatively find out how we study best through trail and error. Most students learn that sort of independent learning when they reach university. So you're ahead of the game! The self-awareness about your learning style will benefit you when you reach there. Be proud of it, and although it can be tough, big up your self-awareness and diversity! No one else thinks like you, you have something unique to offer.
