Hi, I hope you have transferred to your school of choice or at least narrowed your options. I started attending Chamberlain this January, and I like it a lot so far. Some people say the professors at the Addison campus are more "involved," but my professors thus far are very passionate about their fields and students. They are approachable as well, and we have great discussions. I like the overall atmosphere of the school and the focus on nursing, although you may be taking non-nursing courses with DeVry students so there is some diversity, too. It is a for-profit school, and it is a subsidiary of DeVry. However, I researched it and it has the proper accreditation. I am going for my BSN, which is nationally accredited by CCNE. I posted a link to the organization below.
As for the HESI, it's not rocket science and I did not even study for it. The subjects I was tested on were fresh in my mind, though, as I had recently taken the classes. There is an on-screen calculator, and physics is not on the exam. Also, your pre-requisite classes are considered when examining your scores. So if you did not take a class, admissions may be more lenient. I would still recommend looking up sample questions for the other categories. I also recommend brushing up on your conversions and measurements. Overall, I believe it is similar to the TEAS test. I heard the HESI was easier. For the HESI, Chamberlain tests you on math, reading, grammar, anatomy and physiology, chemistry, vocabulary, and biology. Here is a link to the FAQ.
