Hi adnan.afzal,

Since you have only 2 days left before your GMAT, I'd suggest that you don't do anything too crazy - focus on light review of the material. Don't "cram." Don't take any full length CATs. You might find it useful to go back and review your first CAT, redoing the questions that you got wrong.

Your practice CAT scores vary rather significantly from one another, so its tough to gauge how you should perform on Test Day. You could very well hit your goal, but at this point there's no way to be sure.

As to your question, the number of correct answers is NOT the actual measure that matters. There are a number of factors that go into the calculation, including the difficulty of the question, whether you were expected to get it correct or incorrect, the relative position of the question (early, middle, late), whether the question even counted or not (some questions are experimental and are worth 0 points), etc. Rather than could up the number of wrong answers, instead count up the number of questions that you got wrong due to silly mistakes. THAT is an area that everyone needs to work on.

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