i passed the first time. I had Tiam as an instructor and his lessons had worked for me plus he is patiend and fair. Hes instructions are detailed and consistent everytime and beacuse of that i just didnt know how to fail even though my nerves were overtaking me at the day of the test. I highly recommend Tiam, if you want to pass he is the man. If you have determination to learn then he has everything else to add to your achivement. ..
