3) The Registrar's Office is NOT there to help you... go there understanding that it's sole purpose is to mess up your records every single semester and keep you from graduation for yet another semester. If somebody behind the desk at this office claims to have fixed any of your problems in your transcript or your class registration, demand to see the changes in writing and signed by them affirming that they were the ones who made the changes. If you do not, a few weeks later you will get a call from a random department saying that they have just dropped you from courses X Y Z because of clerical errors on your part. Always keep the paper trail handy, or you will be blamed for every mistake you didn't make.
