I already answered this question in my previous reply to this thread. The answer is yes.
I apologize if I misunderstood something you said.
I have know idea because I have never looked at that material.
I have not reviewed all the methods the various other sites use but based on the feedback we have received (for the cost which is nothing) many feel it is a good place to start. Also, the forum is a big part of the learning process here. It exists mainly to help the users work through the times they get stuck and just need a small “assist” to allow them to complete a challenge. I would say that is one of the more unique qualities of Free Code Camp. We literally have thousands of users who have helped out a fellow camper to learn the concepts taught here. I have not found such a community as supportive of people new to coding anywhere else.
99% of the campers here have all struggled at some point when going through the curriculum. Being able to ask questions and get hints about how to approach a problem, is one of main reasons I kept me coming back to continue working through the various sections of the curriculum. Almost 2.5 years later, I now try to help others in the way I was helped back then.
