It may not be you. You may be more advanced and need to be challenged more, or maybe you're like me: your grades reflect that you're smart, but then you turn 40 and realize how big a joke your school was, so now you question how smart you really are. Anyway, don't let anymore time go by. Talk to your school counselor about your difficulties and your parents. There are so many more resources available to you than there were to me. You could probably find so many tips on study habits, memory training, even hypnosis recordings. Exhaust all these before you let anyone talk you into any medication!!!
