Nowadays teens are using the internet and mobile phones much than before. Most of them are using the internet for the wrong purpose. If students keep some PDF books on their phone and read in their free time, I assume that would be great. Here are the PDF books of class nine and ten. Student can collect their textbook from here and keep on their phone. Class 9 & 10 have a total of 30 books on the syllabus. We added here all the books.
