Hey little bro you moving up to secondary school. Imma give you three things to worry about. First, most of your friends will go to a different school. I know you have been with them for a while, but you can always make new friend! Secondly, remembering all your new classes. It wont be that hard, what i do is remember what's around the class. Lastly you got to worry about the teachers. you will have different teachers now for each subject. the teachers have their own personality like you do. The only thing you got to do is be yourself, and always be respectful towards them. Other than that you don't have to worry about anything crazy. You got this!!
