Suppose you have already been taught the theory on certain topic or you have studied that from some sources. Now you are practicing to solve some problems. Imagine two scenarios. In the first one, you are taught a method to solve problems and few problems are practiced. You learn a method. Another method is taught to solve another type of problem and thus you learn another method. This way you solve many problems, and you also learn many methods of solving them. Now, if a question is given to you, you may try identifying a suitable method from all the methods that you have learnt to solve such questions and then apply that method to solve that. This is quite a common way of doing bad in Mathematics as one can select an unsuitable method to solve a question. In the second scenario, you get a problem and you yourself try to solve this. If you are able to solve this in one or two attempts, you learn something. But if you are not able to solve this so easily and keep trying that your
