Tough question as there are pros and cons. I already have a BSBA and I have one more semester to go to finish my MBA and have wondered in this current and future market if it will pay off. While the book knowledge is valuable it is not a replacement for experience gained by the act of doing. You could also just buy the books and learn the material on your own and forgo all the papers, tests and stress. After all so much of the work is reading and then applying to projects that may or may not be interesting. The most important factor is how good the professor is. If you get a bad one then you will not learn as much as with a good one and it makes it not worth the time and effort. This is just my opinion though.
I would write more but I have a 12 page, single space, 10 font, Times New Roman not including cover, abstract, graphs or figures, references and appendixes paper to do over something completely useless
