Hi Brian & Brian and the rest of your Team. I passed my lab exam yesterday in Brussels and I want to thank you for your great Workbook 4.0 which I used for preparing. Especially the Technology Labs and the great explanations in the lab solution guides helped me to prepare so well that I passed on my second attempt. Best regards
