Zandra,

PMI is quite clear about this: The questions on the exam are 40% Predictive/Waterfall/Plan-driven and 60% Adaptive/Agile/Hybrid. So having a solid working knowledge of Adaptive is a must.

Zandra,

Your best bet for preparation would be to use a high-quality exam simulator. I know that the one the PrepCast has mimics the PMI exam in format quite closely. Using an exam simulator will simultaneously help you:
1. Give you a very good idea of "mix" of the exam between waterfall and adaptive style questions;
2. Help you understand the language of project management <-- this was key for me
3. Give you an idea of how the questions are worded in the exam.

Good luck!

The new outline emphasizes predictive, adaptive, and hybrid approaches. My background is mostly traditional waterfall (construction/engineering).

For those who understand the new breakdown better: how much agile/hybrid do I really need to know? Should I be investing significant time learning Scrum and agile principles, or is the exam still primarily testing through a predictive lens with some agile flavor mixed in? Trying to allocate my study time wisely.
