At Babson: Pass/Fail is not an option at Babson College.
If a Babson student wants to take an Olin/Wellesley Course pass/fail they need to follow their policy in declaring that and it will be reflected on the Babson Transcript.
At Olin: Olin courses can be taken as pass/no credit but it is up to the home institution if they will allow this grading option.
At Wellesley: Wellesley courses can be taken credit/non. Credit (CR) requires a grade of C or better.
