Does the word “calculations” make your chest tighten? You’re not alone. In this episode of the RD Exam Ready Podcast, Zak Kaesberg, RD, helps you tackle one of the most intimidating parts of the exam — math. You’ll learn how to confidently approach breakeven point calculations, when to use each of the two key formulas, and how to practice with purpose. With relatable examples, pneumonic tips, and a positive mindset, you'll see that “good enough” math can be more than enough to pass the RD exam.

Struggling with your Biochem? In this episode, Zak breaks down the core biochemistry concepts you’ll need for the CDR exam — with a focus on what actually shows up on test day (no deep dives, just the essentials).

You’ll learn:

• The inputs, outputs, and locations of key metabolic pathways
• How your body uses and stores glucose through glycolysis, the TCA cycle, and glycogenesis
• What happens in fasted vs. fed states, and how hormones like insulin and glucagon play a role
• How to study biochem effectively with diagrams, stories, and active recall techniques

Whether biochem feels overwhelming or you're just looking to simplify, this episode will help you study smarter and feel more confident.
