Graph discipline decides scores here. The tool below drills the chains from your own notes.
WeSolve+ reads the whole document and writes the questions for you
Upload your PDF, photograph your notebook, or point the camera. WeSolve+ writes questions from that material, explains why each answer is right, reads the chapter back to you as a podcast, and remembers every item you missed until you own it.
The tool below is a small browser-only tool and it is not WeSolve+: paste a few lines and text rules turn them into cards on the spot. The real app, the one that uses AI, is behind the link above.
Unit 3 model pieces, from your own notes
This is a browser-only tool, and that is all it isIt splits the text you paste by rule, and nothing else. WeSolve+ is a different thing entirely: it reads your whole PDF with AI, writes the reasoning behind every question, speaks the chapter back to you, and remembers what you missed so it can return it. Try the real app now, free!
Paste a passage and the rules return cards from it. The course outline is invisible to the tool, so completeness is decided before you press the button.
The model is a translation machine, and the input is always a story
A confidence surge, a new tariff, a housing boom: each event lands on exactly one curve. Aggregate demand moves when spending components move; short run supply moves when production costs or expectations move. Classifying the shock before touching the graph is the entire first point of most free response parts.
Draw the graph the rubric reads, not the one in your head
Labelled axes, both curves, the equilibrium marked, the shift arrowed, the new equilibrium marked again. Graders award the picture separately from the prose, and a correct story with an unlabelled sketch leaves points on the table. The habit is mechanical and worth building until it is boring: label, shift, relabel, conclude.
Gaps are distances with names, and names carry the policy
Output below full employment is a recessionary gap; above it, inflationary. The name matters because it selects the prescription: expansionary fiscal policy for the first, contractionary for the second. Answers that jump to policy without naming the gap skip the link the rubric checks, and the link is one sentence.
The multiplier turns small pushes into larger movements
New spending becomes someone's income, part of which is spent again, and the multiplier sums that chain: one over the marginal propensity to save. Tax changes multiply more weakly than direct spending because the first round is partly saved. Comparing those two sizes is a recurring short answer.
Stagflation is the model's hardest case, and the exam knows it
A supply shock that raises costs shifts short run supply leftward: output falls while prices rise, and demand side policy then faces a trade off rather than a fix. Prompts about oil shocks are testing whether you move the correct curve, because pushing demand around cannot repair a supply problem cleanly.

What does AP Macro Unit 3 cover?
The aggregate demand and aggregate supply model: shifts, equilibrium, output gaps, the multipliers and fiscal policy.
What shifts aggregate demand?
Changes in consumption, investment, government spending or net exports. Price level changes move along the curve rather than shifting it.
What causes stagflation in the model?
A leftward shift of short run aggregate supply, usually a cost shock, which lowers output while raising the price level.
How does the spending multiplier work?
New spending becomes income, part is spent again, and the chain sums to one over the marginal propensity to save.
Which policy closes a recessionary gap?
Expansionary fiscal policy: more government spending or lower taxes, shifting aggregate demand rightward toward full employment.
Can I build questions from my own Unit 3 notes?
Yes. Whatever you upload sets the boundary. Photograph the pages or send the chapter as a PDF and the questions stay inside it.
