Hello,

There is no logic. Board is trying to adapt with the situation which has made us know how to maintain sanitation and decrease human interaction.

it is not possible to change end to end in a moment. it takes lots of time to make so that the process will be same as it is used to. They have to keep them as confidential and process it.  There are many cyber breach and those also needs to be controlled.

when a application or webpage  is made to handle inputs from millions of students then server needs to handle else it will crash and student can't appear the exam. it will loss of student.

All of it is lengthy process and it takes time to adapt in a simple yet in a protective way.

Hope it helps!
