1. The Official Answer Book is Separate: The main textbook does not include answers. You must buy a separate "Answer Key for Minna no Nihongo Shokyu II" (which often costs an additional $15-$20).
2. Self-Study Overload: Many learners cannot afford classroom time. Without a teacher, checking Renshuu B is impossible because the exercises are not multiple-choice; they are open-ended sentence creation.

4. Speed of Correction: Waiting to find a native speaker to correct 50 sentences from Renshuu B can take days. An answer key provides instant feedback.
