I don't know if they offer it at other campuses or not. Romeoville is the closest to me so that's where I took it. They use the Kaplan admission test and only look at the Math and Reading scores. The test also has science and writing portions (more like grammar
/interpreting) but they don't factor those scores in.
The reading was pretty easy for me...just read 3-4 paragraph essays and answer questions about the intent of the writing. The math had lot of fractions, decimals, conversions, easy word problems. Math is my weakness and I passed it. I used the Kaplan Nursing test review guide and it helped prepare me for the math session.
This is all for the Accelerated program so I am just assuming it is the same for the "regular" BSN but you should double check it's the same process.
