Another reason why students fail tests is because teachers incorrectly teach their students due to lack of experience in that lesson, they also lack the skills in order to make students pay attention to lessons. It might also be because of the age difference between teachers and students, which makes it difficult in some cases for the teacher to connect to the student. Some lessons end up boring because the teacher cannot create an interesting lesson in which the students not feel bored, and pay attention in class, and finally increase their test scores.
