Starting high school is a big change, but can also be a bit scary and exciting at the same time. What you are going to notice is that the school is much bigger and there are going to be a lot more people. It might be intimidating at first and you are not going to know where to go and where your classroom is, but just remember, everyone else who is starting is going to be feeling the exact same way. As far as meeting people, say hi to the people that you sit next to in your classes, and make jokes about getting lost and turn the awkward, intimading situation into something funny. Basically, break the ice. You will see that after about a week or so, not only will you be much more familiar with the school, but you will already be starting to make friends!! The key is to keep a positive attitude!
