I just finalised reading SAFe 5.0 Distilled and I am thinking about Certified SAFe® Release Train Engineer certification. I am wondering, could I pass this certificate directly, or I need a low level certification, for example Scrum Master? Should I buy the course from training company (providing login to SAFe community), or it will be enough to buy individual SAFe community membership and pass throught all the learning matterial available there?
As well, would it be useful to pass it now or to wait for 6.0? Any info on when it could be launched?
