<p>Do you mean you have started the semester, are past the add/drop period, and are planning to withdraw now? If that is what you mean then you will probably have to pay back a big chunk of the aid for this semester. At this early stage in the semester you will probably have to repay nearly all of it. Even aid that has already been used to pay tuition and fees for the current semester will have to be repaid, so you will be much worse off as you will owe money for classes you are not completing. As sk8rmom said, talk to your FA department before you do anything.</p>
