I don't know do you guys have this problem. My summer school session started today. I take an English Reading and Written Composition class along with a Tennis Course. Each of them at least 2 hours. I don't think I will have a problem to be participated in tennis class, but I do in English class. Today our teacher gave us some introductions to this class with explaining his syllabus rules. While being participated in the class, I was thinking about some other things. This led me which I could not be concentrating in class 100%. I wish to get an A for this class; I want to do it the best. Do you guys know any of well-known medicine that can make your brain concentrate on just one thing and clam down your hyperness? Because while listening to what teacher said, I was thinking about other things at the mean time. So I do need a medicine to clam me down, not to let me think other goofinesses.
Don't tell me just to do soem excercises or whatever, name the medicine for me. I am in emergency.
