NOTICE: If you are on a mobile device, turn it into landscape mode for easier handling. Scrolling is also a bit tricky but there are always several exercises of this kind on one page, so make sure to figure out how to scroll conveniently.
Do not worry too much about grammar here. I'll explain a few things here and there but I don't expect you to learn these. Everything that matters will be explained to you in crystal clear language in this course. See these exercises as games of discovery and not as a challenge or competition.
Also try to explain in your own words what you have learned in this lesson.
