This summer, hang out with your friends / family as much as possible. Hit the gym. Enjoy your summer, there is no better preparation than relaxing then. During the school year, get a locker and pace yourself. Additionally, make a good group of friends, and ask for help from upper years when you feel like you’re drowning. Stay positive. The worst thing you can do is get overly bogged down and succumb to the pressure. Pressure is inevitable, but don't crumble. It gets better.
