After I pass the exam I found that two main reason will lead you pass the exam :
1. respect & trust your mind.
If you have good mind you need to trusted because this will make you way of think going in correct way.
In short "First Head"
2. Tools & Techniqu.
This the second golden advice for everybody, you need to highly concentrate and udnerstand them very well because will reduce your threat on non passing the exam.
