In my opinion, coaching has its own uses and disadvantages.

If we talk about the classes I to VIII, there really is not such a big need for a separate trainer to coach the student. We must understand that a coach or a trainer is required to prepare the student for some major examination. So when we talk about our school system, the major examinations begin only from class IX. Coaching institutes definitely do a great job at making the student run. They try to make sure the result shows up. Thats their only job.

The school studies are quite sufficient in terms of their content and number of periods allotted for preparation for the examination at hand. Most of the teachers in schools also have sufficient knowledge to train the student for the exams. So it is not really the lack in value addition from the school system that is to be blamed for growth in the number of coaching setups these days.
It is something else.

The student has been trained to go to school as part of a regular routine. He has to go to school whether he makes use of that time or not. And, as far as preparation for examination is concerned, there is coaching or tuition in the evening. So the student makes this a routine… to go to school unprepared, come back empty headed as if nothing really happened there with some homework to be done, and then tries to get real value from the coaching. Even the student is not to be blamed here.

In fact, there is no place where ‘what is the right way to prepare for your life and examinations?’ is taught. The school and coaching are only aids to prepare the child for the exam, and both do their duties quite satisfactorily, but thats not all. The student in the early years has to be taught HOW to study, WHEN to study, HOW MUCH to study, how to MANAGE TIME and WHY to study at all. What he should expect from the school and what from coaching. This training, everyone thinks is not useful and time wasting. But I surely feel that if I was given this training in my childhood, I would have saved a lot of my own time and would have been more happy and stress free.

As I said, school does bring in its own value. So the student must focus hard on whatever is being taught in school (for school studies), and then put all focus in the evening in coaching (for competitive examinations). Arts, science, commerce, it does not matter. There are competition exams in every stream now-a-days.

For choosing the right institute, one should only look at how near the coaching is to ones house and how much time is he going to spend there (because self study is the most important thing). Cost should never be the criteria. Time is everything, once lost, never comes back. Money lost, comes back.

While going to school, the student must prepare well for the class thats going to be held in school in advance. So much so, that the student must do a thorough reading of the chapter thats going to be taught in school and take his doubts (whatever was not clear) to the school to ask the teacher. If this is done by the student regularly, performance of the student will improve drastically.
