Why raw Gemini & ChatGPT fail Cambridge Economics
Raw AI gives polite chat bubbles and hallucinates mark schemes. Marginal delivers deterministic, syllabus-calibrated Cambridge examiner marking, diagram integration, and teacher cohort analytics.
“Assess whether governments should always support the provision of merit goods in markets such as those for education or health care.”
Raw Gemini & ChatGPT
Uncalibrated Generalist LLM Chat
Gemini broke down the 12 marks as: AO1: 3/3, AO2: 4/4, AO3: 2-3/5. That weighting does not exist in Cambridge! Official CAIE 12-mark essays are strictly AO1: 2, AO2: 6, AO3: 4. Candidates preparing this way study the wrong syllabus skills.
The candidate included an explicit subsidy shift diagram (S → S1, P → P1, Q → Q1). Gemini did not even evaluate the diagram, treating critical Level 3 economic graphical reasoning as plain text.
“This is my estimated breakdown, not an official Cambridge mark allocation. One important caveat: you haven't included the exact question.”
ChatGPT admitted it did not know the official CAIE bands or the exact question context.
The Result for the Student:
- Lost in a chat sidebar with 50 other random queries.
- No syllabus chapter cross-referencing.
- No school or teacher visibility.
Marginal Examiner Desk
Grounding: Verified against 5 Cambridge Syllabus Sources
Marginal actively parsed the candidate's subsidy diagram: Axes: P/Q, Shifts: S → S1, Incidence on PED. Verified against CAIE textbook standards and credited into Level 3 analysis.
What Worked
Consistent focus on command word "always", valid public choice theory counter-argument.
What Cost Marks
Confused MSB > MPB with producer viability rather than consumer underconsumption.
“Refine the explanation of positive externalities: explain that consumers only consider MPB, meaning market equilibrium output is below socially optimal output where MSB = MSC.”
