Your question puts me in a state of shock.
Since both Engineering and Media requires high level of concentration and persistence.
As an engineering student, apart from lectures, you would be engaged in practicals that would consume most of your day, which at the end I dont think you would have time to focus on Media course.
Similarly during the media course, you would be expected to carry on with internship and that too would consume your day and it would be impossible to appear for engineering lectures and practicals.
Even if you somehow manage, it would completely strain you.
