Stop worrying about taking notes, losing track of what you've learned or working out what to learn next. This course guides you through the Mandarin language step by step.
Each new question adds a tiny building block to what you already know rather than introducing entirely new sentences and telling you to memorize them. Instead you can intuitively build up an understanding of the language through incremental logical steps.
Each word introduced is repeated throughout the course using a spaced repetition system. That means first at roughly 10 seconds, then 30 seconds, 1 minute, 2 minutes, 5, 10, 20, 40, 1 hour etc until it becomes become fixed in your mind. Sentences throughout the course deliberately make use of vocabulary you learned earlier, so words are naturally revised without a deliberate focus on doing so.
Grammar, tones and pronunciation are all taught but never drilled. Instead they are incorporated into each question.
