First of all, don't be nervous about tomorrow's exam, keep a normal mind, don't be swayed by considerations of gain and loss, and continue to prepare for the exam. As the saying goes: sharpen your gun when you get cold feet We should pay close attention to review all day and night, grasp the key points and review in combination with the teacher's explanation. Don't stay up late at night, have a good rest and prepare for tomorrow's exam! God bless, I hope you get good grades in the exam and lay a solid foundation for future study!
