These decks don't teach — they navigate. Every CED topic gets one page: what to focus on, how much it's worth, how the exam asks it, and where to go next (video, past paper, vocabulary). Built for self-study, not lecture.

The three FRQ types you will face

① Design an Investigation

Propose a procedure, identify variables, and analyze the resulting data.

② Analyze an Environmental Problem & Propose a Solution

Name a specific, realistic solution and justify why it works.

③ Analyze a Problem with Calculations

10% rule, NPP, LD50, energy conversions — with units.
