Can I have a engineering graduation without leaving my house? How it works?
No, likely not. Generally there would be classes online, but you'd be expected to attend seminars, "class" educational "events", possibly even a final, things like that. And I'm not sure how many undergraduate distance learning programs there are; though I guess I suspect there are a few.
You really should do a distance learning course with some residential schools, where you get to do experiments/ field trips. Its only proper for a course like Physics or Engineering. Maths, you could do at home, no problem. I did my Physics degree by distance and I regularly went to residential schools for experiments. It wouldn't haven't been a good programme to do otherwise.
