Disclaimer, or, what to do after Duolingo Czech:

There is no single method or approach that will get you fluent. Clozemaster is meant to be used as a complement to textbooks, classes, tutors, and other resources. It can be useful at any level from beginner to advanced, and is an excellent resource as you play through something like Duolingo Czech or as the next step once you've completed your Duoling Czech tree. But Clozemaster isn't meant for the complete beginner. It's most useful for intermediate Czech and advanced Czech learners, or at least once you already know the alphabet, pronunciation, and some basic Czech grammar. That said, language rules are meant to be broken. Clozemaster is the best way to level up your Czech and learn more vocab faster than you ever thought possible.
