Omg that 8th grade boy is taller than me now

I am 16 yr old boy and 5'7(171.5 cm) and the 8th grade boy is 5'11 in just a month. Last month he was slightly shorter than me but today he was taller than me and it was quite noticable and i felt short next to him. He hit his puberty fat because he has a lot of pimples on his face and also a almost full grown beard. I still dont have beard but have moustache now. He looks like a 12th grader more than a 8th grader and he looks older than me. His voice is also more manly than me. He talks with me with sarcasm always in such a way that he thinks i am a small kid. Suppose if i ask who has more beard me or him, he says 'u have more' but in reality he has much more than me. This shows that he thinks i am a kid
