Does this sound like I have adhd/add?

I'm not hyperative or anything. But I always make mistakes on everything at high school. I can never do anything without getting something dumb wrong. I NEVER can pay attention and if I try... My head starts hurting in like 6 seconds and I lose attention. When I'm reading I can't remember or understand the last line I freaking read and when I try to concentrate on a book assignment I never can concentrate or comprehend. I'm advanced in my reading comprehension scores and stuff but it doesn't show in my work which is what my English teacher told me. I honestly am tired of my engineering design class too because I forget everything I learn. I bug all my teachers with 500 questions and my classmates r annoyed. This is not the same in my fave subjects though. I really want to know how others do everything in 10 minutes and I am the last one to finish unless I guess because of my horrible attention and concentration skills. I have been drinking coffee for two days to school and it helps but of course by my 3rd period I'm slow.
