I went to college late in life. We had Python programming class which I liked but I couldn't concentrate in a class with people talking even in low tones, key clacking, phones beeping. Exams were the worst but I got permission to use headphones. At first I tried white noise then pink noise but brown noise is what I found the best. I needed maximum concentration and the entire hour to finish the coding exam. To my knowledge I don't have ADHD but I wouldn't doubt I have it in some form.
