GMAT 575 – 5 Wrong in Quant & Verbal but Only 40th Percentile?

I just passed the GMAT and got a 575, which is not great. I still have time to retake it, but my concern is with how they graded my test.

Essentially, here is what happened: in Quant, I got all the questions correct except about five. In Verbal, I also got all the questions correct except for five. However, I only received around the 40th percentile on both sections.

Is this normal, or should I contact them to ask for a review?
