does it really give awards to winners and has anybody singed up and won?

It’s real, but here’s the thing – any scholarship that is easy to apply to and is available to everyone will get a lot of applicants. So it’s real, but it might take a good investment of time and energy to win the specific scholarships that are offered through the Common Knowledge group. My advice – try it if you’re interested, but don’t rely on it exclusively… especially if you’re not planning to spend a lot of time cranking away at the quizzes.
This doesn’t look like a good use of time.
It is a 501©(3) nonprofit organization, so that’s one sign of legitimacy.
Sometimes, a scholarship may be too specific that not many students are eligible to apply. For instance, a descendent from a certain country going to study a specific field. Just try to find something like that.
