# Lecture 03. Case Analysis of LLM Application Services
## Notice of New Lesson Postings
Hello, students! For this course, **47** new lessons (across a total of 5 sections) are scheduled to be posted sequentially. Since I am producing multiple courses simultaneously, I am proceeding by posting **a little bit of each course alternately**, rather than uploading one entire course at once. Below are the posting principles and the schedule for each section of this course.
> For your reference, the lessons being posted now are not entirely new content, but are part of the production of **revised editions (2nd or 3rd editions)** that reinforce existing lectures.
## Posting Principles
- Currently, I am rotating through a total of 19 courses in order (circular method), posting one lesson per course alternately.
- Postings are made on weekdays (Mon-Fri), with a total of 5 new lessons uploaded across all courses per day.
- For this course as well, the next lesson will be posted each time its turn in the rotation comes around.
- The posting speed may feel slow compared to other courses, but all courses are progressing together in the same manner.
