Quantitative Reasoning

After the GMAT, when they provide you a raw score and a percentile, how should that interpreted? Say, Q50 and 92% percentile. Does that mean that everyone who gets a Q50 sees a 92%, or do some people with a 50 actually see 93% or 90%? If the answer is that everyone sees the exact same percentile, then it seems like the GMAT raw scores, at least, are not extremely granular (maybe this is common knowledge already).

Thanks!
