How do adcoms analyze transcripts?

<p>Hi.
I'm an international student so I have a very different schooling system and curriculum in my country.
We don't have class rank or GPA calculated so my transcript will only have my mid term scores and finals for all years. What I need to know is that what impact will bad 9th grade final scores have on my chances to get admitted into top colleges (HYP, etc). Otherwise my scores are good and 11th and 12th grade scores are very good. Other than this, my standardized test scores (SAT II's) are all 750+, just so you guys know...
