Certificate warning or something
So, it says this at the certificate: "Italian Certificate
Take a 15-minute Italian test, and get a Duolingo certificate to show off your language skills (see an example). You can do this multiple times, at any point in the course." --- You can do it at any point in the course. What they fail to mention is that while you can do this at any point, it still features all sorts of words that haven't been covered yet. Personally I thought it was a big test of the things you've covered. It's different than earlier, where it was clear you shouldn't do this unless you're advanced at the language. But now it's in a beta phase, and with the new wording I thought you could do it at any level now (successfully). Instead I just threw away the lingots.
