I am planning to get certified in PI:
1. I am just wondering is there any PI material specially designed for the PI certification exam? so the study can be focused.
2. Also is there any collections of all the PI sample exam questions?
3. Some questions have more than one correct answers, such as one question has three correct answers, what if among the three answers you chose, one of them is wrong, do you get any mark for the two correct ones at all?
Your input will be greatly appreciated
