I was in 8th grade (let's say 2 years ago,because I'm a sophomore now) so what you should do is "STUDY" have a good impression on teachers don't get int trouble and just don't give up,8th grade is where they teachers will be tough because They're preparing you for high school so always try your best and never give up on things! Hope it helps
I graduated high school in 3 years instead of 4. And let me tell you 8th grade is nothing compared to your high school years. Don't worry about fitting in cause I promise you when you leave that school you'll barely talk to ANY of them. I don't talk to any of my friends in middle school and only talk to 1 friend from high school and i just graduated this June. When you leave, nothing and no one matters. It's what you've done and the grades you got that'll matter.
