practice skills

Hello!
how many skills I can learn. My computer stopped me after "questions" (Italian). Can I learn more?

Sounds like a bug. There are many lessons after that unit.

I suggest you ask Duolingo's troubleshooting team in the troubleshooting forum:

Or if you go here and scroll down to the bottom there's a contact us button:
