The best tip I got for my P's test was "drive like a pussy" lol.
My tip (assuming you know how to drive already and just want tips for the test): The P's test is meant to test your ability to drive safely. You will not necessarily reflect the average driver, so don't worry about going too slow (5-10km/s under speed limit) or any other peer pressure. Show them that you CAN be safe when required i.e. in the test. Even my driving instructor (hired for ~10 hours to prepare for test) was like... "you can drive normally now that you have your P's" (making fun of how the way people drive in P's test is not realistic at all).
