Federal Tax Considerations for Health, and Life Insurance?

[Joshua]

I am trying to find info, or some kind of guide I can study, because I am trying to get my Texas health, life accident license. On the test, there are 14 questions that consist of these two subjects and I get nearly all of them wrong, and have failed the test two times now. If I could capitalize on these two sections I would pass by like 10 points. I have been studying on this online tutor, learninsurance.com but it doesn't have barely any info on these sections. Any help would be much appreciated
