The year I transferred into business I ended up with an A in coms, A- in Acct 317, A in Stats 217. I would say you should be prepared to put in a pretty solid effort in all of them as they are very work intensive.
Irvine is a great prof but he does not hand out As. I had him for audit and it was tough...did not get an A there haha.
Acct. 317 poses a problem I think for those who do not understand the financial statement accounts and debits and credits in the first 3-4 weeks. Make sure you get on top of it early and it is manageable. If you fall behind it gets tough because the concepts come up really fast and assume you know the basics.
"I believe that banking institutions are more dangerous to our liberties than standing armies. If the American people ever allow private banks to control the issue of their currency, first by inflation, then by deflation, the banks and corporations that will grow up around the banks will deprive the people of all property until their children wake-up homeless on the continent their fathers conquered."
