Just took and passed ACMP.
Here are my suggestions for passing.
1. Take IAW and SWDI or the Bootcamp. If you're serious about learning this, these classes are the best way to do it. They teach you the material and then get you doing labs to deepen your understanding.
2. Read the class manuals and commit them to memory. Even the little notes on the side that seem unimportant. More than 1 question comes from those little notes.
3. Read the VRDs. Alot of the info is in the class, but every once in a while a little nugget pops up.
4. Take the test. If you fail it, use what you see in the test as a study guide for your next attempt.
