As a person with a Degree I would say no, it's not.
The most important things you should know in college are:
1. Find the most important points in the bunch of information.
2. Learn how to negotiate.

There're lots of different online courses you can complete in a few weeks or months besides spending years in college. However, you cannot become a professional doctor or lawyer without a degree. Also, I believe that if you don't what to do with your life after school, you should go to university. By the end of it, you gonna completely understand what you truly want and even start doing it!
