I'd be happy to write a 200-word SEO description for your product. To create the most effective description, I need some information about what you're adding.

Could you tell me:

• What is the product? (e.g., NCERT textbook, question bank, lab manual, etc.)
• Which subject and class/grade?
• Which board? (NCERT/CBSE/UP Board)
• Any special features? (solved examples, MCQs, practice papers, etc.)
• Key benefits for students?

Once you share these details, I'll craft a compelling 200-word SEO description that highlights the value, includes relevant keywords, and appeals to students and parents looking for affordable study materials.
