Eh, wrong leh. Statistics from the TP website show that CDC has
the highest passing rate. SSDC is second. 
Anyway, passing TP really depends on many factors. I'd say it's 50%
driving skills, 50% other things like tester, weather and road
conditions, pedestrians, other vehicles, etc.
No doubt about it, some testers are stricter than others, so it
depends on who you get. But all of them look out for two things:
(1) pedestrians and (2) blind spots. Safety is #1, so present
yourself as a safe and confident driver, and you will pass. Don't
freak out, or they will fail you thinking that you will similarly
freak out when you drive next time!
