What will be the format of the RRB online exam? Will it consist of a mix of questions from all sections or will the sections be separated?

Hi Prasanna,

As per the notification, the sections will not be separated in the exam. There will be a mix of questions from all the sections/topics.
It would be a good strategy to prepare for the exam by taking mocks which are in this format.

Check out a few practise tests here:
