Hey! So, let’s start with the obvious, here, being simultaneously African-American, first gen, AND male will already turn the heads of admissions officers. You also have a wonderful ACT score, and while your GPA is definitely low for the schools you tagged (Ivy League and similarly selective schools), there have been successful applications with those kind of numbers. Also, you are still in the top 10% of your class, which colleges like to see.
In terms of your EC’s/awards, there is not a ton of info for me to go off of. I think that if you have been able to make really meaningful impacts with ADHD, and have demonstrated high achievement and interest in writing, then they’re great. I absolutely agree that you should not put down your ECs as a reason for a low grade (maybe you were referring to your ADHD there, not sure). Colleges want to see you be able to balance a heavy workload while being involved on campus, so none of your writing should try to convince them otherwise.
However, your ADHD sounds like a perfectly valid reason for lower grades. It might actually be a great opportunity for you to use the additional info section to explain your struggles with it, and how it has allowed you to emphasize with others with ADHD, and motivated you to help others. If you end up doing this, just be sure to include your growth and ability to succeed academically despite your ADHD - you don’t want the officers to think that it will greatly inhibit your academic ability when you’re in college. Just my view, others are welcome to disagree.
I recommend you start looking for fit. If you really care about attending a prestigious university and that is your #1 priority, then you should apply to a ton of reaches (with some matches and safeties ofc). If you are instead more concerned with how you will fit in and what school will best enable you to thrive (prestigious or not), then I suggest you start by looking for reaches that you love, and then adding matches and safeties that are similar. For example, if you love Brown and its open curriculum, consider schools that share that quality among a spectrum of selectivity.
You seem like a perfectly qualified candidate with a lot of things going for you already. I am assuming you are a Junior, so I recommend focusing a ton on your grades (do NOT retake the ACT, your score is great), and working hard on your essays over the summer. If you want my help with the writing, I am basically a veteran essay writer since I applied to 17 schools this year (lmao), so I would be happy to help. Good luck, and keep me posted!
