"Knowledge", its not just a word it defines something that we have to acquire and have to learn through our life. In past we use to go to "Gurukul" to earn knowledge and learn something of our interest. But, Nowadays, we have schools and colleges for that. And there is also one thing which is also increasing i.e., Coaching Classes. These classes are like we’re going to our second school. And I think the procedure of taking admission in coaching classes is also same as school. Means we have to give an admission test and have to get good numbers to get selected their. Schools are OK at their place because they give us certificate of something that we achieve, but not coaching classes they just want money.
Nowadays coaching classes are just for making money, its like a business. And the main "customers" of these classes are parents not the students. In my knowledge, there is not even a single coaching classes which don’t demand any money. The teachers in coaching classes are not toppers of there college and that’s a fact that no topper wants to be teacher, means not in age of 25-35. And one thing that I will tell you that the teachers in coaching classes are not so friendly and solve your doubts. If you go to KOTA which is I think HUB of these coaching classes there are separate teachers for teaching and doubt solving. The teachers who solve doubts have a answers guide of the study material that they’ve given to students which is provided by coaching classes. And another thing is that the batch in which they teach you have more than 250 students means there will be 250-300 students will be there with you in a single batch. So how could you get the knowledge for which you have paid money. And the toppers that you see in newspapers after result of Jee Mains, Jee Adavance etc., they study on there own and give results and credits have been taken by these coaching classes who does nothing just gives the same notes that they are providing from 10 years. And also for your kind information I’ve studied in Allen career institute in KOTA for one year after that I took DLP(Distance learning Program) and achieve my goal of getting selected in IIT’s.
So according to me coaching classes are just a waste of money but good for only those students who can work hard in studies(as nowadays every student is bright) and those who want also want to go to coaching classes but couldn’t afford have to take DLP(Distance Learing Program) as I does to achieve there goals.
