There are 2 things
1) That you do not like the school, your class room , your class fellow, teacher & grounds.
2) You do not want to study.
You can think that what the reason is.
If you do not like the school, it can be changed. But study you have to do it.
Education gives us insight, how to think?
What is good & what is bad. Read dua in morning and get prepared. Inshallah you will go to school happily
