Graduate from Beta?

Hi guys! just a quick question out of curiosity and maybe ignorance.... Does anybody know what does it take for a beta course to become a complete course (Duo grows up!)?

the progress bars havent moved even a bit so quite some time!

Have a nice day everyone!

We measure a few things (such as the number of times mistakes are reported), and when the metrics reach a certain level we take it our of beta.

Thanks for the answer!

My guess is enough people doing the language lessons, reporting problems and correcting problems over a predetermined time period.

Wow! You guys are speaking a foreign language. What is a "beta course", what are "progress bars" and what are "metrics"? thanks

Yes, what are metrics? Is that the number of people taking them? I have been avoiding the beta courses until they're made "alpha;" is that wrong?
