Hello Akshay,

I think you must first understand how the test works. To start with, GMAT is a Computer Adaptive Test(CAT). So every question you get has a different difficulty level and consequently different score attached to it. Take for instance,

On a scale of 10(relative value),lets say you face the first question worth 5 points.
So if you answer this correctly, you move up the ladder, face a tougher question say 6 points, and if you answered the first one incorrectly, you fall back the ladder and get a question of lower value attached. So throughout the exam the computer keeps on adjusting itself to your level and that's how it calculates your score.

I feel that you are very new to this whole concept. I would suggest you to start working on your errors and you can concentrate on your scores at the latter stages of your preparation.

Hope this Helps
