I am interested in having German courses. How much time do I need to complete a level for example? How much time does it take to complete 2 books (A1-1 and A1.2)?
我对有德语课程很感兴趣。例如，我需要多少时间来完成一个级别的课程？学完2本书（A1-1和A1.2）需要多少时间？
You can consider the Theory course with 20 or 30 lessons per week. Focus is on theoretical teaching. No practice units are included in the morning, it's highly recommended to attend the application-oriented practical course in the afternoon. It takes approximately 8-9 weeks to complete one level. There are 6 levels in the language: A1, A2, B1, B2, C1, C2. It might take up to 16 weeks to complete two levels.
您可以考虑理论课程，每周20或30节课。重点是理论教学。上午没有练习单元，强烈建议参加下午的应用型实践课程。完成一个级别大约需要8-9周。该语言有6个级别：A1, A2, B1, B2, C1, C2。完成两个级别可能需要16周的时间。
