Hi All,
Practice CAT scores are only as realistic as YOU make the process of taking the CAT. The GMAC Scoring Algorithm is proprietary, which means that no other Company has an exact match for it - while each Company's CATS have some built-in 'biases', 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").
Here are some details to consider: When you took any CAT (even the GMAC CATs)...
1) Did you take the ENTIRE CAT (including the Essay and IR sections)?
2) Did you take it at home?
3) Did you take it at the same time of day as your Official GMAT?
4) Did you do ANYTHING during this CAT that you couldn't do on Test Day (pause the CAT, listen to music, etc.)?
The GMAT is a predictable, standardized Test, so you CAN train to face not only the Exam, but also every aspect of the actual day you take the Test.
GMAT assassins aren't born, they're made,
