TGIF would not have been the same without the blended family that made up Step by Step. From its amazing theme song to making us believe that living in a van was ideal, Step by Step was an iconic gem. That is why we could not get enough of it when we were kids and why people are still finding new ways to discover the magic all these years later. With that, it’s time to test your Step by Step knowledge. We bet even the biggest fan won’t pass this one with flying colors!
