It is clear that in the courses we enroll in, it will be very important that we have the necessary textbooks to be able to follow the classes. In this way, we will be in charge of studying the contents that are recommended to us in order to pass the classes. But we are going to ask you a question, are they textbooks completely necessary?
The truth is that you have to look at this question from different points of view. On the one hand, we must bear in mind that in primary courses the existence of these books is essential, since children are incapable of elaborating notes sophisticated enough to study. It is clear that teachers could give them, but that does not happen.
It is in the upper grades and in ESO where they already begin to use notes and put aside textbooks. It is not done in all subjects, but it is clear that little by little this is being taught way of studying. It is in the university where this is most practiced. In fact, most students tend to make their own notes, something that allows them to study the way they want. All they will have to do is pay attention in class and write what they consider necessary.
The notes are very documents, especially in the higher courses. They contain the information that we must study to pass the exams and courses, so we recommend that, as far as possible, you do them. In this way, you will have new study possibilities.
