I passed the test and got this result :)

Honestly, no :D Actually, I write the text myself and then ask AI if I wrote it right

yep

you can use everything, I think. Just search what you need. You can learn basics by videos, or maybe you like more books? Then just type: good books to learn …

My advice for future: just try to use language for things that interest you. It doesn’t matter what it is. Youtube videos, films, books, games, anything!
