Hi Sweetlyf,
People have answered your question above about the penalty on unanswered question(s).
However, it seems to me that there are also two misconceptions in your idea about scoring:
1. Even if you have the same number of questions wrong in two different sections, you may not get the same sectional scores. Quant section scoring is generally less forgiving than Verbal or DI.
2. Even if you get the same section score in two sections, you will not get the same percentile. This is more likely due to the demographics of the test-taking population, and can be easily observed from the percentile tables on the page:

Hope this helps a bit.

Hi,
Just wanted to understand the logic of penalty for not attempting a question in GMAT. For eg I was attempting official mock and there was some time-management issues during Quant section in which I could not attempt the last question. What was surprising was my overall score for Quant was 66% and 80 Score (in which there were only 2 wrong answers - 18/19th question and 21st unanswered). I found the score little harsh and not sure of the reason. My previous mock score was 96 verbal percentile (with 2 questions wrong) and both times Quant was the first section for me (so assuming starting baseline is same). Some details would help as it has really pulled down my overall score with other 2 sections above 90%ile.
Thanks
