From now on, she has one lesson there every school day. I thought she'd be going once or twice a week, but she's properly joining their English class and will sit in on every lesson for the rest of the year.
I'm not sure if she's nervous or excited or both. Probably both. I reminded her that it's an amazing opportunity that she should make the most of, but only an opportunity, and not something to stress out about. :)
Will look forward to hearing tonight how it went.
