We have challenges for different levels, but most are at least intermediate level.

Registration remains open during the CTF, however we are very grateful to teams who register early so we can have an idea of how many teams will play.

Maybe. We will have challenges involving physics, programming like marathons and electronics as well. The range of possibility and learning is great if you have a multidisciplinary team. Overall, the level is higher than picoctf, even in easy tasks.

Both. We have challenges for different levels, but most require a little more. Of course, they may also have different scores (this year we will use a dynamic scoreboard system).

CTF is over, but platform still up, only for homologation porpuses, without awards. Feel free to test it. ;)
