Yes! The beta curriculum is still being developed, so things can change often. However, once it’s to a point where the developers feel it’s ready, they’ll replace the current curriculum with the new one.
I started this cohort thinking the beta was working for everyone, since the goal had been to release it by 12/25/2017. A few people seem to be having problems with it, yourself included. So, at this point, all I can suggest is to do what you can, using outside resources as needed if the beta isn’t working, do the current curriculum instead, or wait to catch up with us once the beta is released.
Since this first Responsive Web Design section is mostly projects and one will not need the fCC site to do those, I recommend those having trouble with the beta site read every link that’s shared here, finish the projects, and hopefully the beta will be released by April.
Also, looking over the beta curriculum code and opening issues to help fix it, if one can, will help as well!
