Hi csuntico
The official site has a description of the things that you will be tested on

You can also find sample questions on this page

I really like the level check tool on this website
http://www.tanos.co.uk/jlpt/levelcheck/
It has vocab, grammar, and Kanji tests.
This site has some practice quizzes and a lot of other information
http://www.jlptstudy.com/N5/
I started studying 日本語 last month, and looking to take the N5 exam too. Good luck and let me know if you find any other good resources!
