NVS CS is a free Android app developed by CBSE Delhi under the Education & Reference category. It is an examination information tracking and monitoring system designed to help CS students upload all their activities on examination day.

The app's interface is simple and easy to navigate, making it accessible to users of all levels. Upon opening the app, users are greeted with a dashboard that displays all the necessary information needed for uploading activities. The dashboard contains options to upload images, video, and audio recordings, allowing users to document their activities in various formats.

Overall, NVS CS is an excellent app for CS students who want to track and monitor their examination information. The app is free to download and use, making it accessible to all students. However, it would be great to see more subcategories added to the app to make it more comprehensive and cater to a wider range of students.
