For a general idea, the admission fees for a private school for Class 8 could range anywhere from Rs.20,000 to Rs.70,000 or even higher as a one-time charge. Besides this, there will be other charges like annual fees, which could be in the range of Rs.20,000 to Rs.35,000 annually, or even more depending on the school's facilities and offerings. Some schools might also have quarterly or monthly tuition fees.

The cost of books for Class 8 will depend on the syllabus (CBSE, ICSE, or State Board) and the publications. On average, you might expect to spend around Rs.2,000 to Rs.5,000 for a complete set of textbooks and notebooks. This can vary based on whether you opt for new or used books and the specific titles required by the school.

Overall general expenses for a Class 8 student would include tuition fees, cost of books and stationery, school uniform, transportation (if applicable), extracurricular activities, and other miscellaneous expenses. Depending on the school and your lifestyle, these expenses could range from Rs.3,000 to Rs.10,000 per month, excluding the one-time admission fees. It's always best to check the specific fee structure and other charges directly with the school you are interested in for the most accurate information.

I hope this helps.
