please let me know this time KVPY is online which options is batter online or Offline ?

Hi,

It depends on person to person.
If you comfortable with using computer and u have given the tests on it than u must go for it.
If not than the convectional mode is always an option.

The reason behind the preferance of online mode is that its handeling is easy, you have to click to choose the option insetad of filling the bubble which saves a lot of time.
You can also mark questions for review which will lead u to those questions instead of searching them in the paper.
