@maceel Start with the Main Level 1 challenge and work your way from there. It should give you some understanding on what you’re supposed to do to go through the exercises. If you come across a problem you can’t solve, give it some thought, search the forums and online. However, and I really can’t stress this enough, do not look up whole solutions online. If you do you’ll get the points of course, but you won’t learn anything from it. And this is all about learning.
Good luck, happy hacking!
