Hi TX from another Texan!!
Here is the best site I found for the NET test. It is so much better than wasting $30.00 on the book from ERI World.

I didn't know about this site before I took my test, and I passed in the 92 percentile, but I know I would have done so much better if I had looked at it. The practice tests are just like the NET was. Good luck~
