C104 might be a better choice than W131. It has a slightly better grade distribution, but you would probably be fine either way. http://gradedistribution.registrar.indiana.edu/
As far as other classes go, you should definitely get some gen eds out of the way. If you are not coming in with any AP credit, you will need a natural science class, 2 arts and humanities classes, and some way to fulfill the world culture requirement. http://gened.indiana.edu/Students/requirements.html
You can take classes that double count for A&H and WC, so I would recommend taking one of those each semester. I took CLAS-C 101 Ancient Greek Culture and REL-A 210 Intro to the Old Testament. Both were fairly easy A’s. I would also add an easy natural science like PSY-P 101 Intro to Psychology.
Another suggestion is to take K201 first semester and K303 second semester. K303 is very easy, and there’s almost no way you wouldn’t get at least a B if you can get at least a B in K201.
