How to get a sick note
Ask your parents to write a note.
Many schools don't require a doctor's note for sickness, and many doctors will not write formal notes for school absences. Your parent or guardian can write a sick note for your teacher after you recover or drop it off personally.
Be sure that the note written by your parent or guardian has the date of your illness. It should also address the teacher and have a brief explanation of why you are absent.
