<p>I notice how almost everyone on these boards posts their weighted average, but doesn't every school weight grades differently? If so, then how can anyone's GPA be be compared to someone elses? My school weights an AP class with 1.15 and an honors 1.04 and that's it, thus making my UW GPA=3.76, but W GPA=3.90 ( That includes 3 AP Classes and all the rest honors except for 2 regular classes)</p>
