One of the things I've noticed from other posts is that various schools and locations seem to use different exams to qualify students for entrance to nursing schools. But as a general rule, there is some commonality about the level of competence they expect a student nurse to have.
I took the test on a whim with a friend, and I did very well. However, I also enjoy math and science, am married to a man who does too, and so we enjoy lots of thinking type entertainment--reading, TV, and talking. So my mind is already set for doing arithmetic in my head for my own amusement.
I realize this is not everybody's choice idle activity, though.
Check the book stores for a preparation book. The ones with sample tests and answers worked the best for me when I was preparing for skills assessment tests some years back, and I have bought several as gifts for my kids and friends when they were anticipating such exams.
Barron's and ARCO are the publishers with which I am familiar, and I can comfortably recommend them. Working those tests will give you an idea of your skills level, where you might need some extra practice and mostly will help to relieve your worries about the type of questions you will be asked. Use a timer and only give yourself the same amount of time as they will give you (you can trust the book's suggested amount of time). You can always go back and look at those questions you didn't get to, but you will see if you need to speed up, you can slow down, or what the value will be of skipping stuff you don't know--or would take longer to answer--and coming back. This maximizes your score because the questions are typically all worth the same number of points.
The more questions you actually answer, the better your chances for a higher score. (Unless they tell you that you will lose points for "guessing"--never heard of that with a nursing exam, but in some other settings--where a wrong answer counts against you more than a right one counts for you--never leave an answer blank
. If there are four choices in a multiple choice question, picking SOMETHING gives you at least a 25% chance of getting the points. Picking nothing assures you of getting nothing for that question.
If you have recently taken your prereqs (within the last couple of years, anyway), the odds are good you will do well enough on the sciences. As for the math portion, if memory serves (I took the test about 2 years ago), if you can do basic math (they give you scratch paper and a pencil, but, I think, no calculator--ask them if this makes a difference to your frame of mind, so you won't be shocked and do worse because of that), you will be able to do these questions. What they used to call "story questions," the ones where you are presented with info and asked to construct and solve the problem for the answer, were, in my opinion, the most challenging (and most satisfying, but that's me...
