Hey, thanks man.
Well, I took another Princeton today, and you were absolutely right.
I scored a 49, but even then i had a total of 11 wrong. So, it is proved that the number of questions you get wrong has no bearing on your score. It is the number of tough questions that you get right. Most importantly, the questions were really tough, in comparison to the previous test.
The last score, was probably due to my misconception that I just have to keep the total no. of wrong answers down. Previously, I would just skip a tough question because i knew that I'd done pretty well in the previous questions and was under the cloud that just 1 wrong answer wouldn't hamper my score. And my word it did!
This is a huge mistake, and I'm glad I've realized it sooner rather than later.
So this is probably a good lesson to all the GMAT takers under the misconception that the number of questions you get wrong is a vital part in determining your score. Hence, you need to try and get as many tough questions right as you can!
Cheers And Thanks a ton man! Owe you one!
