When we do a summary, it is common to remove (and therefore avoid putting redundant text) those parts that we think are not going to be useful to us. This includes all kinds of concepts. We will be in charge of deciding whether a part will be useful to us or not. However, it can also happen that something that is going to be of interest to us does not seem like that at first.
First, before starting to make a summary, it is recommended that you take into account the main factor on which the content will circulate, that is, the theme on which we will focus. Knowing that, we can now summarize. We will have to store all the content that we find useful and that, of course, have to do with the subject. If not, the summary might not be, having to study more than necessary.
There is a mistake that many people can make. we talk about when we remove a sentence in order to make it as short as possible, that in reality that content is going to be useful. It can cause us to study less and, in case you don't forget, get a lower score on the exam. You must be very careful with this.
In the event that the opposite happens, that is, that we put more content than we should, all we have to do is study more. At first it should not be a major problem. Although it is true that it can cause a certain discomfort, in the event that we do not like to do it.
For the rest, make a summary it's not complicatedAlthough you must take into account what you think is necessary and what is not. Do not forget it, since your note is at stake.
