I know exactally how you are feeling right now about the reading comp. on the NET. Don't feel so bad I took it 3 times already and still did not pass that part of the test (well passed but the schools want higher 65+). I score great everytime but, that reading comp. gets me too, everytime. However, I am not giving up and if this is really what you want you should not give up either. I have talked to alot of people about this, even wrote letters to ERI (that is the company who writes the test). A few of my co-worker (all RN's) have told me there is no way it can be done the way you/we are doing it. However, there is a slight little trick..... get the book and READ very carefully what it says in the NET prep book (cost about $30.00) just exactally how it describes finding and look for the main idea, inferential, theme, etc. in a paragraph. Example, the "main idea" of the paragraph is always listed in the authors 1st sentence of mthe paragraph, then the rest just elaborates about it, bla, bla, bla. It's the only, only, only possible way to pass.
Good Luck! And please do yourself a wonderiful favor get the book, it's the only way to pass!
P.S. Keep me posted...hope this helps.
