If you learn from instructors who pick up at AMK or YCK but the test centre is at Ubi, I think it's a wastage of time and money to drive from YCK to Ubi for training and back from Ubi to YCK. It is almost one hour. I'd better spend my own time and transport fee to go to Ubi to train rather pay instructos to acompany with me. That day went to CDC Ubi, it's really shock and surprised. There are plenty of PDI with cars at the both sides of the street. Majority charge 24/26$ and some even lower than this, only a few charge as same as those at YCK like26/28$. Some enrollment fee is 30$ only. I think for those looking for instructors and who want to test in Ubi can go there to have a look.
I think this Mr. William's training centre is at Ubi,,and his passing rate for the 1st timer is not high..
