What to do with different GPAs

<p>I used Collegeboard's way of calculating and got one GPA, but when my school councilor gave me my GPA, it was different. (.25 lower...) I asked her about it and she said it didn't matter since "all school recalculate the GPA upon admission anyways." Is that true? I mean, .25 is a pretty big difference, especially for the colleges I want to apply. What should I do about it?</p>
