No, you cannot typically edit your graduation percentage in the college correction window. The graduation percentage is usually a verified record from your previous institution and is considered a permanent part of your academic profile.

If you believe there is an error in your graduation percentage, you should:

1. Contact your previous institution: Reach out to the relevant department or office at your previous college to inquire about the accuracy of your graduation percentage.
2. Provide supporting documents: If there's a mistake, be prepared to provide any necessary documentation to support your claim.
3. Request a correction: Once the error is confirmed, request a formal correction from your previous institution.

It's important to note that the process for correcting a graduation percentage can vary depending on the institution's policies. It may involve submitting specific forms or providing additional documentation.

I hope this information helps you.
