Does IB prepare students for college significantly better, or is it just more work?

@EarlVanDorn Considering the IB exams are externally marked - an exam taken in New York may be marked by a reader in Little Rock, Leeds, Hong Kong, or any other place you’d care to name - I don’t understand how these teachers could have known a student’s grade.

Are you referring to grades for a student’s internal assessment (or the language course equivalents)?
