Surely you have already done it and you have not even realized it. When you do your notes, that is, when you summarize the text that you will study later, most of the time you have to go to a clean medium that allows you to study in a more comfortable way, without distractions.
However, what you do not know is that with these contents you can also teach more people. Imagine it. Keep in mind that, when you finish the exams for which you will be studying, the notes will hardly be used, so you can dedicate them so that other people can learn the same as you.
We will explain it in a different way. When you pass the course, try share the notes with someone who wants to study a topic. We are sure that, if he dares, he will begin to read the content that you have given him and, in this way, he will also be trained in the same specialty as you. In this way, you not only learn, but you also teach.
Although it may not seem like it, the work you will be carrying out will be very important. You may even teach someone who does not have the resources to do so, thus achieving a Experience more on the subject. It is, without a doubt, an excellent idea that you should not take a step back from, since it is also a good action.
We encourage you to do this the next time you finish an exam. We would not be surprised if you saw each other surprised in different ways, or even that you learn, together, many more things.
