How does one tell if they have ADD or ADHD versus just not good in a subject? I'm currently entering 3rd year in Engineering and many of the classes themselves do not interest me at all. It is very difficult for me to study since I start making careless mistakes if I sit still for too long. As a result, my grades are not as great as I would like them to be(even in non Engineering classes like psychology and math). I have trouble sitting still during tests and often daydream/feel like walking out of the room. The thing is that while I do lackluster in classes, I love the subject and studying these on my own, then going to a professor if I have questions or need further direction. Even in self study I will read some exciting theory or practice and pace around the room to daydream about its possibilities. This has culminated in some projects that impress professors, even though I do subpar in classes on those same subjects. My Question: Should I get medicated for ADD and (presumably) gain more focus/better grades for classes at the risk of losing my creativity and excitement for the subject through outside projects? It seems like the only way to get into a top Grad School or get a good Corporate job. Thanks.
