first day posting, talking about my day at college

am i the only one who hate those people who think they're smarter than you're at college or school? i mean dude i get it you have more knowledge than me can you stfu now? 

i only have 8 days left till the exam and i don't know a lot about what I'm studying and this dude just stands up and began to joke with the doctor about nonsense, and the doctor laughed and continued joking with him.

don't get me wrong I'm not a nerd, i just don't want to fail and i only have 8 days left, like come on just sit down let me focus on my shit.
