Availability of Dual Language Course for NCERT Class 3
There are dual language (Hindi-English) courses available for NCERT Class 3 textbooks. These courses aim to provide a comprehensive understanding of the subjects in both languages, catering to students who are more comfortable learning in Hindi or English.

Video Content
While the course material may be available in both Hindi and English, it is possible that the videos provided are only in English. This could be due to various reasons such as availability of resources, production constraints, or the target audience of the videos.

Explanation
It is essential to understand that the absence of Hindi videos does not necessarily mean that students cannot benefit from the course. The course material itself is designed to be bilingual, allowing students to grasp the concepts in both languages. Additionally, students can always refer to the textbooks for further clarification in Hindi.

Benefits of Dual Language Courses
- Enhances language proficiency in both Hindi and English
- Helps students understand concepts better by providing explanations in their preferred language
- Encourages inclusivity by catering to diverse linguistic backgrounds
In conclusion, while the videos may be in English, students can still make the most of the dual language course by utilizing the bilingual course material and referring to the textbooks for further clarification in Hindi.
