FAQ
Common questions about the course
Can I learn without a programming background?
Suitable for beginners and learners of different ages, at your own pace
The courses are designed for beginners and do not require prior JavaScript or CSS knowledge; age is not a restriction either. You should be comfortable with basic computer use and willing to practice consistently. Difficulty and study time vary by course, so we recommend watching the free previews before choosing a course.
Is the course focused on tool usage?
Learn the required tools and setup while understanding real project workflows
Courses cover software installation, environment setup, account registration, and AI tools. The goal is not simply to memorize one tool, but to understand how a project moves from idea to completion through practical tasks. Tools change over time, so refer to the latest course content for current instructions.
How do courses work, and when can I join?
Learn mainly through recorded videos and notes, starting whenever you are ready
Courses are delivered mainly through recorded videos and written materials, with exercises or supporting resources in some courses. There is no fixed start date: you can join at any time and set your own pace. Course length, update frequency, and practice format vary, so refer to each course page for details.
Will I be able to complete projects independently?
Courses emphasize hands-on work, while outcomes depend on practice and project scope
Courses use practical tasks and projects to help you build experience. Whether you can complete a project independently depends on your practice time, foundation, and the project's complexity. Start with small features and combine them into a complete project. Refer to each course page for its specific exercises and learning goals.
