First, please allow me to express my sincere thanks to Brian Dennis, Brian McGahan, Petr Lapukhov, Scot Morris, Anthony Sequeira and all staff members. Not only the workbook, mock lab and support have enabled me to pass the R&S lab exam, but also they enhanced my work skillset to become a better IT professional. I really appreciate all you do for me and for all candidates. Now I can tell everyone I know of that it's worthwhile to travel down this path no matter what it takes.
