Transfer Credits for College Courses taken in High School

For current Cornell students or others who have had experience with this:
How do transfer credits work? Is there a way to figure out if a certain course at a local (reputable) university will translate to an equivalent course at Cornell?

There is a form on the Cornell site with instructions specifically for this. You also need a copy of the syllabus for each course. I believe it varies within each college within Cornell what they might accept.
