🎯 If you are still considering taking the course
Now, the question is no longer 'whether to use AI coding tools' but 'how well you can handle them.' Over the past 7 months since its launch, more than 9,000 people—including not only developers but also marketers, planners, researchers, data analysts, and students—have mastered Claude Code through this course. This means even non-majors can follow along.
Recent Course Reviews
I am a non-developer, and I was extremely satisfied with the course. The content is structured so that it can be applied in many different ways. It doesn't just explain Claude Code's features; it covers practical tools used in the field, from the Terminal to Git, MCP, and Supabase, so I really learned a lot in just one course. Since it covers everything from basics to advanced topics, I felt that this one course is enough. This quality at this price? You won't find it anywhere else. If you want to build something with AI, just pay for it.
📣 Next Story - We are preparing the 'Practical Version'
If you've grasped the big picture of Claude Code through the basic edition, the next step is 'how to use it well.' I am currently preparing Claude Code Perfect Mastery: Practical Edition. It will cover how to properly utilize Claude Code in real-world practical scenarios.
If there were moments when you thought, "Why isn't this working?", problems you couldn't solve until the end, or topics you wish were covered in more depth, please leave them in the comments. These scattered questions will come together to form the curriculum for the practical edition. For existing students, we plan to provide a special discount coupon when the practical version is released. If you take the basic course now, you will be able to continue to the next step at a more affordable price. 😊
✍️ To those currently taking the course
If the lecture was helpful, a single-line review would be a huge source of strength. Leaving even a short, honest review will serve as a great guide for future students and motivate me to create even better courses. If you haven't left a review yet, please take this opportunity to write just one line!
Once again, the discount ends at midnight tonight. Don't miss out on the last price of the first half of the year.
Thank you ☺️
