Scholarships can be reduced for a number of reasons depending upon the rules/regulations for the specific scholarship. Most scholarships require full-time enrollment but others may be pro-rated based upon credit hours. Other funds may be based upon actual charges you have incurred with the university.
When you receive a scholarship, you should be sent a letter or email notifying you of the requirements for each scholarship. Be sure to read the information carefully so you understand the details.
If you have questions about a scholarship, contact the Office of Financial Aid or the Scholarship Coordinator for the academic college that awarded the scholarship.
