It is possible to can approval for transferring math courses. Keep in mind that this process may take up to 4-6 weeks, and plan accordingly.
If you have taken a math course at another institution in the U.S. or abroad, you may have the course evaluated by the Math department to determine if it is equivalent to a math course at IUB.
In addition, if you plan to take a course at another institution in a future semester to transfer back to IUB, you may get preapproval for that course.
