Some people opt not to take medication and use coping strategies alone. Some medicate for school but not to study on weekends. A lot depends on you, the severity of your ADHD, how it is impacting you, and how effective you are finding the meds.
There are kids who really can’t learn without meds. This doesn’t sound like you. However, it sounds like you are naturally bright, and it can become challenging when you are faced with concepts you can’t grasp immediately because you may struggle to concentrate as you work through them. That’s a tougher situation.
Using coping strategies is a lot of work but work you will need to do at some point in your life anyway, so DO understand that meds are not a silver bullet.
Personally, I worry about the impact of taking ANY drug on a regular basis and particularly ones that affect the brain. I would not hesitate if it were absolutely necessary, but in your case, the decision- which is 100% up to you, is probably more nuanced. You may want to have this conversation with the neuro-psych who did the testing, with your therapist, and with your pediatrician to get more input.
