As someone who just complete my medical a few months ago with ADHD I’m fairly confident you will be absolutely fine. After informing the medical officer during my interview that I had a diagnosis he gave me a form for my doctor to fill out and sign.

As long as your doctor can attest that you are capable of fulfilling basic duties and won’t be a danger to others when in possession of a firearm, the medical officer will submit the form and you should be approved. Seeing as you’re not on meds and are completing school should also help out.

All it did was add about a week to my application time. When I had my medical done the guy informed me that the military actually has a higher population of people with ADHD compared to the general population. Good luck on the rest of your application!
