If you want more practice with bonfire-like challenges, http://www.codewars.com/
is awesome. Once you solve a problem, you get to see how every single person on the site who solved the problem before did it, and the solutions can be voted on, so you can sort to see the best solutions. There's a lot of benefit to being able to see dozens (or hundreds) of solutions and seeing the variety of approaches. Also, on your profile there, you can enter "Free Code Camp" in as your Clan and be on the FCC team.
