Hi Anantjit,

When you take a CAT, if your goal is to receive a realistic score assessment, then you really have to be strict about HOW you take the CAT. The more the 'CAT-taking event' deviates from what you'll face on Test Day, the more likely the score is to be inaccurate (and in most cases, that means "inflated"). As such, you should make sure to take a NEW CAT each time, with the Essay/IR sections, away from your home, at the same time of day as your Official GMAT, etc. Taking an individual section (either Quant or Verbal) 'out of context' of the full GMAT is NOT a realistic experience. You won't be allowed to do that on the actual Exam so you shouldn't be practicing that way.

Beyond those details, it's important to remember that taking lots of CATs will NOT make you a better Test Taker. A CAT is really a 'measuring device' - when used correctly, it will give you a realistic score and help define your strengths and weaknesses, but it will NOT help you to fix any of those weaknesses. To raise your scores, you have to put in the necessary practice and repetitions. The CAT will show you whether your studies are helping you to improve or not.

GMAT assassins aren't born, they're made,
