I took the NET exam 10/01. I used the 'study guide for the net, the hobet, the help entrance tests by Educational Resources, Inc. I purchased it at our college bookstore for $44.50. I especially liked the begining of the book called test taking stratagies. I actually didn't study before hand but I would recommend reviewing math before you take it. My school's test included lots of fractions. Best of luck and don't stress too much.
