As we all know a students without teachers and additional learning support they will find difficulty to manage study in their own time of self-study.I totally agree in my point of view not all students can work indpendent in their own time if they cannot cope with the method while they studying. For example, if a student have a probelm of extend has vocabulary and repeating the same words ,he should get assistance to help him to check the work if does make sense or not.
