How to Use the Course / 课程使用方法
1. 45-90 minutes per module, split into 2-4 short sessions.
2. Read English + Chinese, then watch the short-video link for each concept.
3. Ask the child to explain the concept aloud before showing the answer.
4. Complete 20 multiple-choice questions; use bilingual analysis to correct misunderstandings.
5. Finish with short-answer/application questions.
6. Difficult modules may take two calendar weeks. Mastery matters more than speed.
建议：每课45-90分钟，分2-4次；先中英文阅读，再看短视频；先让孩子自己解释；选择题后用双语解析纠错；难课可以学两周。
