Talk About Short Notice

So apparently 95$ for an IB Course Test is due TODAY. Talk about short notice!!! They gave us a form about it in October but didn't bother to tell us when it was due, or what it was about, or why we had to pay. And then BAM I get an email saying money is due by today or you have to pay a late fee. Apparently if you don't pay you get removed from your IB Course.....HECTIC!!!!!
