I've been searching high and low for the 2001 NCEES Practice Exam but its a rare one to find. Someone is selling it for $1,995 on Amazon right now. I found it for $50 on Amazon a few weeks ago and bought it 10 minutes after it was listed. When I check on the order a few days later, it said it was cancelled. Im assuming who ever was selling it found out what it COULD sell for so they backed out. I found a copy on Ebay for $150.00 and purchased it Monday, we will see if it is legit. But be careful because I was scammed another time too.
Im not sure what it is about the 2001 copy that is so coveted, but that seems to be the consensus.
Good luck!
