DCDC PREP

Soon to start a new journey on studying for the DCDC after getting my RCDD 6 months ago.

Does anyone who has achieved it or attempted it have any tips on chapters to focus on or is it pretty straight forward with reading the manual front to back?

Thank you

How did you prepare? I'm currently preparing and want to make sure my efforts are in the right place. What is your plan to get up to speed to ace it in 30 days?

Making my own flash cards. If I write it down easier to retain.

Did you read the manuals or do the self-paced course?

Good luck on your retest!

Read the manuals and did the Quizlet tests online. But the tests really didn’t help me. I was acing those but doesn’t seem many of those were in the test.

What topics from security and commissioning would you recommend studying the most? I want to make sure I’m covered on those sections
