I used IEWB version 2-3 to prepare myself for the lab. Compare to other workbooks that I purchased, your is the best. It inches my skill from the basic of Lab1-5 and profess my level at lab 9-13 and harder. I would not make it to the top without your book. Thank you. I will come back for my next track.
