Our app offers a question bank for Level C skills certifications, including refrigeration and air conditioning installation, interior wiring, Chinese cuisine cooking, and more.
In addition, we've introduced a special AI-powered question-solving feature that can answer your questions, offer suggestions, or provide solutions to specific problems, allowing you to quickly find the answers you need. However, this feature is only available for questions consisting entirely of text; AI-powered solutions cannot be used for questions containing images.
We believe our app will be your best learning partner, providing comprehensive support for your exams and skills certifications. Whether you're preparing for an exam or looking to enhance your skills, our app is your best choice.
