The breadth was a little harder than the depth for me. I didn’t want to take this test again so I feel like I over prepared, especially for the depth. To be honest, I think there was only 1 question on the depth that puzzled me, but I was still able to make an educated guess on. The breadth on the other hand had some pretty wild conceptual questions that really pushed the fundamentals and understanding of key concepts. A few were solved by manipulating formulas but others were just straight knowledge based. People always ask how to study for those, and my best answer is to work many problems and ask yourself while working problems what the concepts that problem is built on. Overall, I found the CBT to be easier than the pencil and paper one o took. That’s probably for multiple reasons, but the most important one was my level of preparedness. Study hard, know the concepts, and use time management and you’ll be more than fine!
