Hi mbavignesh,
Test Day is a rather specific 'event', with an established set of details to it. A CAT score is only as accurate as YOU make the CAT-taking experience 'match up' with what you'll face on Test Day. The more you deviate from what you'll face on Test Day, the more your scores can be 'off.' For example, if you skip sections, take the CAT at home, take it at a different time of day as your Official GMAT, pause the Test, etc., then you won't be properly training for what you'll face on Test Day.... and your score results will not be realistic.
1) How did you score on this CAT (including the Quant and Verbal Scaled Scores)?
2) How long have you been studying?
3) When are you planning to take the GMAT?
4) What is your goal score?
GMAT assassins aren't born, they're made,
