<human>: Okay, so, I applied for financial aid and I got two grants. One from my school and the other from the pell grant, however, even though they both cover ALL of my tuition and fees and I'm even supposed to get refunded something like 700$ back I apparently owe the college around 400$.

I thought it may be because I failed a class, but I looked up on my school website how that's handled and apparently financial aid covers class re-takes as long as it's required by my major. It is required by my major since it's currently listed as business administration.The class I failed, was college algebra, I'm bad at math as it is and I missed too much of the class to effectively understand the material. I retook the class, this semester and passed and financial aid covered everything and life was dandy.

Now, It's spring, I have a lab along with 4 classes now though, as opposed to just 4 core credit classes. It's still more than covered by my grants and financial aid, so why is it that I "supposedly" owe the school around 400$. I really would appreciate any help or advice on how to handle this, Thanks.

Can you condense the text into three sentences or less?
<bot>: Got financial aid - it covers all my fees/tuition yet I somehow owe 400$ to the school. Da fuck?
