I don’t really know how the courses are handled. I personally don’t remember the procedure how I switched the courses (probably it happened through a link as I was a tester(couple of moths ago)). I remember logging in and all my notebooks were new (so keep that in mind because you’ll have to redo the C3 and C4).
Maybe these threads can help:
But to be honest, I don’t know if the things are the same (have they changed the policy since then) or how are things now regarding that.
Cheers
