What can be a drawback of relying solely on textbooks during preparation?

Relying solely on textbooks during preparation can indeed lead to challenges, particularly in the clarification of complex concepts. Textbooks often present information in a structured format, but this may not always effectively convey complex ideas or practical applications. Some subjects, especially those involving intricate processes or dynamic scenarios, can benefit significantly from diverse instructional methods, such as interactive discussions, visual aids, or hands-on experiences. These methods can enhance understanding by providing varied perspectives and interpretations which may not be captured in written text alone.

Supplementing textbooks with other resources like videos, interactive simulations, or study groups can create a more rounded learning experience. Such diversity in learning approaches is particularly beneficial when grappling with complex material, ensuring students can grasp and apply these concepts more effectively in real-world scenarios.

Other options suggest that textbooks provide all needed knowledge or imply that they are preferable to online resources, overlooking the necessity of varied learning resources in achieving comprehensive understanding. The notion that textbooks are outdated presents a valid concern, but it is not as directly tied to the challenge of understanding complex topics as the selected answer.
