I purchased the R&S Workbooks We, II & III combo package last July. By October I could scrounge enough equipment to creating a working solution for your design. I then began non-stop lab work (which includes a full-time job). I am fortunate to have access to a few co-workers/friends which might be already CCIEs, to examine things with. I sat for any lab on February ninth and received a ARE UNSUCCESSFUL grade. I doubted some of the results I got and after a few days of deep thought, As i requested a re-read. I received the results this morning with this grade changed to PASS! Just wanted to thank you for building such a superb product. Brian Dooley, CCIE #23688.
