Is it worth it to get a real estate license?

[Gerald Jarreau]

I am totally new to real estate and BiggerPockets. I have a condo and have been considering renting it out and moving home with my recently widowed mother to help out and to be able to afford another investment property. I am considering either buy and rent, or flipping the second property. I want to keep my current 40hr a week job for now, but that's about all I know. I am wondering if spending 400 dollars for an online real estate course, and then taking the test is going to be very beneficial to me. I do not have experience in real estate. Can one get a license and work nights and weekends in order to sell either independently or through a realtor? Is it worth it just for the general knowledge?
