Could it be ADHD or something else?!

I'm having an extremely hard time focusing on stuff. If it requires the least bit of thinking, i loose interest. Even if its something i love doing such as reading or drawing, i can't stick with it for more than a few minutes at a time. And in class, i fidget a lot in my seat and often daydream or look around the room. When i try to complete an assignment, i'll do the first two problems then i may start doodling or coloring in the letters. I also get distracted way too easily. Say, for instance, i'm sitting in a silent room with nothing on trying to do my homework. If i hear even insignificant noises from anywhere, i get caught up in trying to figure out what it is. I often lose stuff and don't complete tasks like homework, chores...etc. because i jump from one thing to the other so often. I often get yelled at by my parents for not listening or not turning in my work at school. And when it comes to remembering things, i'm hopeless. Could it be ADHD or some other problem?
