KD Campus E Book is an Android application developed by KD Campus Tech Team that offers free online videos solutions to all questions. The app provides a convenient way for students to access online course materials, as well as enroll in the online book. To get started, users need to install the app from the Android Play Store and create an account using their phone number or email address.

Once logged in, users can add their book by scanning the QR code provided in the book. It is important to keep the QR code confidential to prevent unauthorized access to the online videos. Users can then scan the QR code of any chapter to access all the questions on the page and their online explanation. The app also allows users to bookmark any question for future reference.

To ensure proper scanning, users should place the book on a flat surface and hold their phone on the QR code within the scanner quadrant. Users can also turn on the flash light on the QR code scanner for better visibility.

Overall, KD Campus E Book is a user-friendly app that provides a convenient and efficient way for students to access online course materials and improve their learning experience.
