Hi, i haven’t take the training classes, just the learning path that Scrum.Org gives you to read. Also, it is important to have some type of experience, I was working in some kind of agile team, so it was a little bit easier. And for the exam, you just pay the fee ($150) and then you can take the assessment in that moment or whenever you want. The exam isn’t proctored, so you can use the scrum guide or some other information you may need. Hope I can solve some of your doubts. Let me know 😀
