Confused about high school!!! HELP!!!?

Im starting high school this week and im confused about my schedule! I got the schedule of my cles but do i take all of them everday in the same order or does it change? And also are you supposed to carry your backpack with you to every cl or do you leave it in your locker? Do you get recess in high school and how much time is it? Or do you just get lunchtime and thats it? Help me please!
