If anyone has an  old copy if possible on pdf file of the fundemental practice exam edition 4 or 5. Can I please have a copy emailed to scrappywelds@aol.com? I have a copy of the 3rd edition and either of the next two later editions would sure help. I am buying the 5th edition after the first of the year, if they haven't came out with a 6th edition. The 4th will sure help. If anyone can help me out I would apperciate it.
