Actually this one was special, I'm in a hacking group at my university organized by a teacher, and he orchestrated it all alongside a couple of students. I signed in another CTF just today because a friend of mine who is into it told me about it. I guess I heard about most of them from friends, but you can find a bunch of them on the internet too! You can give it a try with hackthissite.org/ which is pretty similar. Also check up writeups! Good luck haha
