multiple transcripts

I still have some time until i apply to bschool but i was trying to figure where i stand. I transferred twice during undergrad so i have two older transcripts with thirty credits on each and then i have my final transcript from my graduating institution with 75 credits. I did somewhat poorly on my first and second transcripts, but i had a 4.0 from my graduating school. Someone told me business schools all calculate undergrad GPA's differently so i sent a few emails out. Stern was very very clear they would only look at my final transcript to calculate a undergrad gpa, cornell stated to just write my final transcript's gpa, but all the other schools i emailed sent me unclear generic answers so i couldn't really pinpoint their responses. Is anyone here familiar with any other business schools that look at your graduating transcript only to calculate undergrad GPA?
