"Knowledge Levels" refer to the different stages of understanding or expertise that individuals can achieve in a particular subject. These levels often range from basic awareness to advanced mastery. For example, a beginner may have a general idea about science, while an expert can conduct complex experiments and contribute to the field. Typically, knowledge levels can be categorized into four main stages: novice, intermediate, advanced, and expert. Each stage represents a deeper comprehension and ability to apply knowledge. As individuals progress through these levels, they gain more skills and confidence in their understanding of the subject matter.
