I was expecting a score of above 700 but I ended up with this,
Real GMAT: 670 (AWA 6.0, Quant: 48, Verbal: 34
)
I followed Manhattan GMAT and I found their tests quite good.
Manhattan GMAT 1: 640
Manhattan GMAT 2: 710
Manhattan GMAT 3: 700
Manhattan GMAT 4: 520 (left the quant part halfway)
Manhattan GMAT 5: 720
Manhattan GMAT 6: 740
GMATPrep1: 680 (before the actual prep)
GMATPrep2: 740 (The final test I gave five days before the actual one)
In the actual GMAT, I found it very difficult to concentrate at the end. Due to some mysterious reason, I felt fatigued and tense.
I thought about giving the test again, but decided against it. I have just graduated and I am actually trying for the MSc. Program in Finance in European Universities, so 670 may be sufficient. Moreover, my GPA 4.87/5.00 and good recos and essay should be sufficient.
I will try to cross the 700 mark when I appear for my next GMAT (for MBA in 2014)
NOTE: I will advise all to prepare for atleast 3-4 months. one and half month isn't sufficient to cross 700 for most. Even if you master the subjects, the duration of the test may become daunting. Condition yourself to face the test and stay healthy and fit.
