Replying to High schoolers, how do you pass the day by?

Junior year in high school is coming up and my stoke level is a solid 2/10.

I know theres always 1 or 2 classes that are actually pretty chill, but how does one get by all the other ones and still pass the class?

What gets you high schoolers through the day? How do you tune out that one teachers who talks to all the class like their 5 years old? How you do make it to the end of the day and not be burned out?

I need to know or this year is gonna be hell.

Thanks
