$39+
Everything for all four CDFM modules in one purchase: my personal study notes for Modules 1, 2, 3 and 4, plus a practice exam for each module with 100+ questions.
What's inside:
Each item is a downloadable PDF. Read the notes module by module, then test yourself with the matching practice exam. These are my personal notes, not an official study guide. Bought separately, this set would cost $70.
