Help! Need advice for TEAS online study guide

[sunny001]

My husband recently became ill and can no longer bring in a sufficient income, so after 32 years of being out of school and 12 years of running my husband's real estate business (which I hated) I have decided to consider a career as an LPN. I have contacted a school in my area, Eastern Center foor Arts and Technology and registered for the TEAS in May. I've found this online practice link and have attempted some of the tests, which I've found to be quite challenging, if not impossible. I was hoping someone could take a look at the math practice tests and advise as to the similarity between those and the actual test. I don't know if its the fact that I've been out of a classroom for 32 years, but they seem to be confusing annd awfully difficult to solve. My daughter graduated recently from college at the top of her class, and even she was bewildered by some of those math questions! Please help!!
