ok i got a math hsa tomarrow and im freakin about it. Im think about taking dexedrine to take it, or maybe take it today and study for it. Im afraid if i take it today i wont be able to eat or sleep and be too tired to take a test. But if i tke it tomarrow im afraid i might barf or it might acually hurt my score. Basically, do yo think speed is better for scenerio problems like math, or memory problems like in social studies? At this point i dont think ill take any, just wondering if u think itll help?
