If I understand your question correctly, you're asking how you can get a different raw score but the same overall score, or get the same raw scores but different overall scores.

First answer: The difference between a 44 and 46 on verbal is tiny; I believe both of those scores are still in the 99th percentile (or at least very close to it). Since they are essentially the same score, it doesn't really affect the 200-800 overall score.

Second answer: The percentiles change over time, so it's possible that what used to be a 760 is now "only" a 750. I know that 750 used to be 99th percentile, but now it's 98th, for example.

Hope this clears things up!

Thanks for answering but i still cant understand the second one. I thought the same thing but the difference between the dates are only 2 weeks! I still think it is unfair because with 2 weeks difference the same raw scores get differet 200-800 scores.
