I did my IDC course with Matt (Blue Marlin) in Labuan Bajo (Komodo) last month. Before to start the course, Matt provides you the material which it's very useful to study before the course begins. The 2 days preparation were very useful, I really recommand it!!
I really like the detailed schedule which Matt give us at the beginning of the course which it's helping to see a very clear vision what we are going to do but also for the homework have to be done. He is very patient, kind, available to answer at yours questions anytime, he speaks fews languages so it's very helpful if there is something you don't understand well and also he is very supportive. I really felt definitely ready for the IE!!!
Thanks a lot for all your support and your hard work!!
