Hi Aniruddh,
I would like to add my two cents.
If you have seen ESR's of the top scorers here(like that of souvik101990, for example - or you search this forum for ESR), you will observe that the average difficulty of questions presented to a candidate is medium high and goes to on increasing towards high (as candidate with perfect score keeps getting every answer correct). And thus there will almost be no single question with difficulty level 'EASY'. Even if candidate gets a question or two wrong, the next question will be either of same difficulty level (high) or just... just below that (i.e. medium high
or medium) - but ultimately no question of difficulty level 'EASY'.
Having said, what I learnt, I agree with what experts have said here - focusing and engaging one's energies on studies and getting everything correct is best way to get a high score.
Hope this helps.
