Hey @Laurap1228 - it's so exciting to see someone starting on the journey of getting all the weekly challenges done in order. There's a few of us who are on this journey, and quite a few have gone through 30 or even 50 of them, and for me this was one of the best ways to learn the toolset!
Keep on cracking through these - the learning is invaluable, especially if you take a look (only after you've completed your version :-)) at the solutions from some of the community greats and see how they have tackled them. There's so many ways to solve a problem, and by looking at other folk's approaches to each challenge (and trying to replicate them if they strike you as new learning) it really does accelerate learning.
:-) 2 more to go (since you've already done numbers 1-3) and you get your Khumbu Icefall badge (for 5 completed challenges) !
Good luck @Laurap1228 - it's a very exciting expedition you've undertaken.
