Praise be to Allah.
lectures is undoubtedly falsification and lying, and it is a transgression against the lecturer. It is strange that the administration or the lecturers allow this.
The one who is not able to attend the lectures has to try to convince the college to reduce the number of hours of lectures or to overlook absences. As for lying and forgery, there is no necessity in this case that would make it permissible.
And Allah knows best.
