Why should you fill out your planner?

Some people may ask why should i fill out my planner. I got that answer right here, This is why you should be filling out your planner. First of all, It helps you stay organized. If you don't stay organized it will take forever to find something or take forever to do something that needs to get done i learned the hard way. Also filling out your planner helps you remember stuff like test quizzes and homework. You can also use it as your own personal calendar like if you have fact sessions you can put that in and when you turn to that day you will remember oh i got a fact session i better server it before i get a Saturday detention. Also i know some teachers use the planner as their own personal user to remember stuff. Also why shouldn't you use a tool that will help you i learned it the hard way and now if i don't get stuff turned in and get things done i might fail this class. So you should use your planner to stay organized and get good grades.
