You are correct that the GPA will carry more weight - but at some schools rank does carry.
I still don’t understand how you can be on a 4.0 and have a 6.0 weighted. Weighted should still be vs. a 4.0 - but will be higher due to APs. I concur, there’s no way you could be 15% if you have 16 APs - unless you are getting Bs in them. But then your weighted wouldn’t be over a 4.0.
Can you explain your weighting system? Hard to get to that #colleges-and-universities:washington-university-in-st-louis
With a high unweighted GPA, if money is a concern, Alabama, Arizona, U of South Carolina, Miami of Ohio, Arkansas - schools like that would be home runs with lots of really smart kids (not paying a lot of money)!!
