Should I attend Seminars/Conferences that give Certificates upon achieving some number of attendance? The question is self-explanatory actually.

Should I attend Seminars/Conferences that give Certificates upon achieving some number of attendance? And do they have any worth if I/ to put them in my CV?

I'm an undergraduate student currently in Electrical-Electronical Engineering program and every week there are seminars carried out by University/Department and varius events carried out by various clubs. Some of them give certificate upon attandance and some of them require attending the seminar for some number of sessions for certification but I'm not sure if those certificate have any value at all and I want to know if it's worth ditching relaxing after week of lectures for some certificate that can be obtained by literally every single human being that walks in to the hall.

Thanks in advance.
There is some value in attending these Seminars/Conferences that you may want to consider:


It shows that you are "doing more" than the minimum requirements
You may end up adding or emphasizing important keywords in your CV
The Seminars/Conferences you mentioned are from University/Departments and clubs.  If the Seminars/Conferences have any "Name Brand" involvement, such as corporations or other institutions, you get the name of the institution on your CV.
