Score questions

Hi everyone!

Long story short, I changed my major to Nursing & I take the TEAS on Monday. I rented a book since they were grossly overpriced & I'm taking a few practice scores online.

My school said I only need a 50% to get into the program but is the TEAS exam cumulative or do you need a certain percentage overall? Math is a sore subject for me but I'm working really hard & I really want to be a Nurse, so I'm praying I don't fail (which is funny since you can't "fail" the TEAS apparently, there's just a certain level you have to meet, not an exact passing score).

I'm doing pretty ok in Science & I'm out of the park on my English & Reading, so I'm hoping all of that is enough to get me a good score. I know this is an "essential skills" test but some of the questions to me seem odd for a test meant to screen potential nurses. What does the gravitational pull of the sun & moon have to do with Nursing unless NASA has a program we don't know about?
