Biology class... sucks

I love biology. Like i wanna become a doctor or do something scientific, because i have to say, im quite the nerd. But the thing about high school biology is that some stupid high school kids cant behave themselves when they hear about reproduction. Like come on, its science.
But the people in my class are just so obnoxious. Like they had this question about whether koalas had three gential parts (sorry i dont like typing the word out). And im just sitting there in the back of the class like "are you serious?? Like can i punch you in the face?"
sometimes i just cant even with people.
