How to use the podcast

First listen: Play at 1× speed with no distractions. Don't try to take notes — just absorb.

Second listen: Speed up to 1.25× or 1.5× and follow along with the Cheat Sheet or Essentials page open.

Right before the exam: Play at 1.5–2× as background while reviewing flashcards. Repetition locks in VSEPR shapes and hybridization patterns.
