Operations:

automatic validation

is automatically executed when entering validation. All situations that are not of (probably much) interest to the teacher are automatically resolved in the first step. These situations include: a student's course enrollment was cancelled by the study department and then reinstated; a student's study was deactivated, a new study was created, and the student was enrolled in the course in that study. All these operations performed will be listed on the teacher's information page. It is recommended to study this information. If you find something in them that you do not understand, you can ask your study department. A list of study departments can be found at https://is.ambis.cz/studijni/.

add the listed students to the notebook

These are usually students who did not have the course when the notebook was created and now have the course already enrolled. If you do not want to add students (you have a notebook for a certain seminar group only), select "do not add missing students (programmes of study) to the notebook during the validation process" when defining the notebook.

to remove students who do not belong

Note that if the "Date of last change of study status" is close to the current time, it is possible that the study department is, for example, transferring the student to another programme. Wait with the operation, you would lose the contents of the block of students affected in this way.
