For me, the Hacking permission one is the one I tried...
I didnt know how to solve it first...
I tried some things, but when I saw that the cookies are the ones which load with the page(ma kint 2a3rifa be4), i entered the cookies and checked one named password and i solved it...
the other challenges, i was mitil l 2atrash bl zaffe :P
The one abt the batch code, its easy, just a copy paste material :P
but yeah Im now reading the solutions and re-trying the challenges by my self so I can benefit and learn, and be able to compete in the next time
