Education, job prospects, age issue?

Hello, new to the site. But have a question. I’m considering a B. S. in IT Management. Is the degree worth it to some one with little it experience? To manage something shouldn’t you have a thorough knowledge of it? Yet the course description seems to only cover basics. In addition.. I’m nearly 50 yrs old by the time I graduate.. Switching careers. I do have an associate in networking.. But have sadly forgotten most of what I knew..
