Annoying, immature kid distracting me in class? Watch

(Original post by rachelconlon)
I started college this week and I'm taking A-Level Physics. Yesterday this 14 year old boy started our class. He's been fast tracked, and has already sat his maths and further maths a levels. Our teacher placed him next to me as it was the nearest empty space. Even though it's only been 2 days with him, he has really started to distract me. He's a know it all sort of character, and constantly chatters on about basically how much he knows and how he got the questions right etc, but when the teacher is talking or trying to explain something. He's really immature, obviously he's only 14 but he acts like a child. I can barely focus on the teacher with him constantly whispering down my ear, saying completely irrelevant things like "I'm going to look through this textbook to see if there is anything I don't already know" and asking me how I do things because he does them in a different, (he implies) superior way. He also does things like for example we got our homeowkr back and he physically leaned on me to see what score I got and then started telling me that I should have shown my working, etc. I don't want to seem horrible but he is really distracting me and I don't think I an cope sitting next to him for the next 2 years as our teacher has us in a seating plan. What should I do? Should I have a word with the teacher? Should I tell him to be quiet? I don't want to come off as rude to the rest of the class either but he is really starting to annoy me. Thanks for any help
