BEWARE OF THIS PDI
I am currently taking Class 3A lessons with this PDI, he called himself uncle ang and has a blog that advertises his services, number is 91504550. Engage at own risk, if you like someone short-tempered but not thorough in teaching.
For the first few lessons, he was an alright PDI and willing to teach. However, you will notice that he will talk on the phone constantly or watch tv on the car when you are having lessons with him. He doesn't emphasise on safety check (important note! this is important for TP test). He talks a lot and sometimes take up a bit of your time to buy food or talk to his friends while he go and take the number for circuit lessons.
Note: he is impatient and fairly easy to jump into conclusion that you are blaming him or accusing him. Very short tempered! And he has a tendency to verbal insult students (me) in a roundabout way. Beware if you prefer a more professional and quiet PDI to teach you.
He will always change your timing, sometimes at the very last minute and it could be difficult to change your plans.
As I lost details of the payment from my first test, I asked for a breakdown of costs of the expenses for TP and he refused to give me a clear amount of which portion is paid for which part of the lesson/rental. Note: I paid an extra $50 for warm up that he requested and he asked for another $272 for warm up session (again?) and rental of his car. I tried asking him what is the previous $55 for and he just scolded me and say I am accusing him for cheating my money.

And insulted on my physical appearance and then tried to laugh it off like nothing.
He screamed at me and scolded me brainless (he does that during lessons too but anyway!) and insisted I paid for the amount he stated.
I did pass my second attempt at TP but all because my first tester were very detailed about what to take note of and I have been looking through my old bbdc school manual for practical training to ensure everything is in check.
