How to Survive Long Classes w/ ADHD?

I’ve struggled with ADHD my whole life but have had it pretty well managed on medication.

But I still find it super difficult to stay focused in class the whole hour or more.

Those of you with similar issues, what strategies do you use in class to help maintain your attention and keep yourself from getting distracted?

I would get up and go for a short walk but I don’t want to miss the lecture.

Thank you in advance! 🫶
