I have now completed levels 1,2 & 3 of Mark’s excellent course. They are presented in a clearly understood and very professional manner and deals with all the technicalities both in depth and a very erudite way. Mark has a rare gift of sharing his considerable technical talents in an enthusiastic and easily understood way. His video demonstrations are awe inspiring and at the same time inspiring. Your confidence cannot help but improve after engaging with his remarkable teaching. I thoroughly enjoyed all aspects of the modules so far completed, and I await level 4 with keen anticipation. Woul recommend these tutorials to anybody keen to start in this very rewarding craft.
