Aren't you 4th year students happy that you have one more year of this madness?
At my school this is a trend, 5 and even 6 year students are common. The average student takes 12 hrs per semester. I know someone who has been there since 1996 and is still an undergrad, she only take 3-9 hours per semester.
There is also a population who have majored in one thing and then they got to their junior or senior year and decided that they wanted to change their major.
