I just took the HESI today so I thought you would appreciate a fresh perspective. You do not have to take any sciences? LUCKY you! That's great! You will do just fine then..as long as english is your first language..it consists of everything you learn in grade school, literally. It is beyond easy! Reading is a mixture of reading paragraphs then answering questions based upon the information. For example, I had a passage about the Summer Olympics from 2008 in China and a questions was "When was the Summer Olympics held?"...lol...it was super easy and nothing that I would say you can really study for. As far as grammar, just read over what exactly a verb is, a noun, how they are used...but this part was mostly fill in the blank with the correct answer. So it would say here is a sentence.."Bob _ to the store on his way home." Choices: A: Was B: Went C: Going D: Is. Very obvious choices! To me, again, this is not a section you can really study for...its common sense. Vocabulary was not what was in the HESI study guide, it was more everyday words that you will know by simply reading the sentence. There was a couple I was not sure about because the choices didnt really click to me, but that was only a couple. In the HESI study guide I think I spent maybe 1 hour just flipping through the grammar section and brushing up on it so I was comfortable, however reading and vocab is common sense and you will do AMAZING!!! Good Luck!
