Yes dear , It is compulsory to have 75% of attendance in any engineering college .But in most colleges, if one does not have the minimum criteria of 75% attendance, you are not allowed to sit for examinations. Compulsory attendance has been the most debated topic among college students.

Hope this helps !!
