For whatever reason, there will be times when we will not be able to attend to class. We simply cannot because we have other appointments, even more important ones, or because an illness prevents us from doing so. When we miss class there is a lack of attendance. And this, it is evident, is pointed out to us in the file. What should we do so that we do not subtract grade?
If the faults are few, with justify them we will have more than enough (we will only have to present some documents) but, if the number begins to be more or less large, then we must be very careful, since they can affect us in a very negative way. Ideally, we should only be absent when absolutely necessary. And, if we do, that we carry some kind of document that proves the reasons.
We can also do something else: in the event that we know in advance that we will be missing, we will we communicate to the center so that you take it into account and be aware of it. Being warned, although the lack of assistance will be on paper, it will count in your favor, since you have commented on it well in advance.
There are not many more tips on this. If you see that you are going to miss class, communicate it with all the in advance possible. If you cannot, attach some kind of document that justifies it and informs those responsible for giving you class. So they will be aware. Keep in mind that unexcused absences can be quite negative. Do not forget it at any time.
