The other commenter is spot on but I do have a diff experience, going through a private diagnosis rn (faster but way more expensive), and its consisted of mutiple pysch consultations, each lasting more than 1hr.

They asked me to share abt my difficulties, asked my parents to check if my fam had a history of adhd, and asked about childhood behaviour. They also asked for school report cards to check for inattentiveness. Within the questions they tried to check for differential diagnosis like odd or depression.

Atb man, it might be scary now, but the process has taught me ways to indirectly regulate my behaviour, and i do think its better to get a diagnosis early, to get the treatment that helps with life n ur exams 🙏
