There are two aspect of worth in terms of learning. Well BITS distance education is worth in terms of learning because it provides a vast syllabus.
Now coming in terms of value in the industry you will get a call from companies that consider BITS tag but from here come the twist.
Most big organizations won't consider this as degree and HR will reject as many of my friends have faced that and it won't be same as on campus because they will able to identify you have done distance education as a degree.
You can do Ph.D but it depends on the university as top university won't consider the distance education but from the learning point of view its good.
