The user wants me to revise the previous draft. The previous draft had 1246 Chinese characters, which exceeds the 1000 character limit. I need to reduce it to 500-1000 Chinese characters. Let me rewrite, keeping the structure (3 sections) but condensing the content. I need to make sure I count only Chinese characters (not punctuation or English). Let me draft a new version: 1. 门课程解决什么问题
2. 适合什么基础与建议先看哪几块
3. 学完能独立做什么与资料怎么配合练习 Let me write concisely:
