<p>Your EFC and your brother’s EFC will be reduced while you are both in school at the same time. The parent part of the EFC is divided between the number of students in college at the same time. Any part of the EFC generated by the student’s own income stays with that student. </p>
<p>You grandparent living with you may have a slight effect on the EFC. Income protection allowances in the EFC formula are based on the number in the household.</p>
<p>Whether the two situations will reduce your EFC enough to make aid a possibility depends on the total EFC and the cost of the school. Just make sure you take into account that the EFC will increase again once your brother graduates and you are the only one in college, as then the whole parent part of the EFC becomes yours.</p>
