To Build a scalable web application using MERN stack
To build online examination system with good look ux, ui and very easy user interface to take test online
The application should be scaled to minimum user of 10 Lakhs which should be concurrent users on site to take their test
The flow includes login and register and once after the user logins they would be able to see upcoming tests and user should be able to take a test online and the questions should be based on the levels and user can see like ranking of their position based on their current ranking among the all active 10 Lakhs user on the site and finally user should be able to get the all round analytics on the test based on the their performance on overall.
If you read my proposal carefully, please write your perfect project two url of MERN in first line of your bid.
