Replying to ADD and ADHD

Recently its been called to my attention how many kids have "ADD" or "ADHD". NOW I'm not even remotely saying its not a real disease or mental disorder But lately Iv'e figured out how many kids "have" one of these disorders. I have also figured out how many kids will go and get tested or fake the tests so they can get diagnosed with one of these diseases and then get extended test time on exams and even ACT's, IS this ok? What are your thoughts
