Basic Conversational Mandarin Course uses Pinyin (spelling sound) as the teaching focus. There are a total of nine lessons altogether which the student pass the topic quizzes before he/she can proceed further.
Note that you have two repeat attempts to pass the quiz which is usually set at 50% passing grade. Do drop me a note if you are unable to clear the quizzes after three attempts. Note that you will not be entitled to incentive rewards (quizzes and early finisher) if you fail to pass any quiz in three tries.
