Who do you think you are?

My name is Mazhar Siddique, and I’m an 18 year old person, I was born in Brooklyn and that’s also where I live now, though I went to high school in manhatten.
B) one of my main concerns is not getting a good gpa. I fear this cause I’m still adjusting to college, and though it seems a bit easier now, I’m sure it’ll get much harder. Another concern I have is that I wont be able to make friends until very late in my college career, this is because while I was friends with the majority of my high school, they were really nice people, and it was a small school, so I fear that this new setting means it’ll take longer to make good friends. Another concern is trying to join more clubs then just one. There are so many clubs to choose from and most of them only meet during club hours!
C) I feel that without my friends, it means that I have to take more responsibility and not expect my friends to cover me when I’m absent or explain me the lecture if I don’t understand it.
D) Hopefully It’ll make me accustomed to this new environment and allow me to get used to the college life and make more friends.
