<p>How can colleges use GPAs and take them into account for every school has a different system? One high school may have inflated GPAs, where as another high school may have a tough weighting system.</p>
<p>any theories?</p>
<p>The top colleges (and most others, for that matter), spend a lot of time getting to know high schools. Often, colleges have regional adcoms who visit the high schools, study their profiles, and know their regions' schools very well. High school grades are then taken into account alongside the profile of the high school.</p>
<p>what if our district instilled a new weightage system beginning from the class of 09? do top colleges see UW GPA or WGPA?</p>
<p>That's what rankings are for. SAT's also take some part in this as well. If you get A's in all your math classes, but get a 600 on the SAT math, then the adcom is going to question how good your classes really were.</p>
<p>will a 90 in a quarter of math and science hinder my chances at a top school?</p>
<p>I'm assuming a 90 is an A or B, so probably not.</p>
<p>Colleges re-weigh grades, anyway, to put people from different systems on an equal footing. No need to worry, methinks.</p>
