Well, I'm a sophomore at Drexel University and a Computer Science major that is considering switching to Information Systems after this semester. Does that qualify me to participate in this thread?
Deeko, What someone said earlier about the CS requirements looking a lot like an engineering course isn't far off. CS at Drexel are soon going to be considered engineers. There was a BIG issue here recently that the tuition for CS majors would be raised to reflect that of an engineer (a/k/a just another BS way of raising tuition again). Most freshmen who come in here that are looking for a career in computers come in as a CompSci and quickly change over to IS. Last year, my freshmen year, 70% of the entering CS majors dropped by the 3rd quarter to go to another major, mostly to ISYS.
The transition from CS to IS is very easy, requiring only a GPA of 2.75 and almost all the class credits transfer so you don't have to take additional IS-only classes to catch up. The transfer from IS to CS is very hard, however, as you will have to almost start from scratch to catch up in core classes.
My recommendation is to do exactly what I'm doing. I took a year and a half of CS courses and now I'm not entirely sure if this is where I want to be or not. I have the option to switch, if I was an IS major considering switching to CS, I would not have that option unless I wanted to put myself way behind my 5-year plan.
Hope this helped,
CK
