The tool below drills the arc.
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 7 collapse arc, 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.

What you paste is what gets carded. Fixed rules split the text and nothing outside it is known, which makes the paste itself the real decision.
Causes stack until any spark serves
Industrial rivalry, alliance blocs, arms races and nationalist claims load Europe by 1914, and the assassination merely fires what was loaded: the tested skill is ranking structural causes above the trigger. The First World War then runs on industry, trenches fed by rail and factory, which is why casualty scales dwarf every prior war and why the term total war earns its name.
Empires fight the war, and the war consumes empires
Colonial soldiers and labourers from India, Africa, Southeast Asia and the Dominions serve on every front, a global war in the literal sense, and the promises made to recruit them seed interwar nationalisms. Four empires do not survive: Ottoman, Habsburg, Russian and German crowns all fall, and the Versailles settlement parcels their lands into mandates and new states, grievances included.
The interwar order fails its stress test
The Depression crosses borders through trade and finance, and liberal governments' helplessness feeds authoritarian answers: fascism in Italy and Germany, militarism in Japan, each promising order, revenge and autarky. The tested chain is economic collapse to political radicalisation, with rearmament and expansion as the programs' shared logic: Manchuria, Ethiopia and the Rhineland test a League that cannot enforce.
The second war is totaler than the first
The Second World War erases the line between front and home front: strategic bombing targets cities, economies conscript entire populations, and ideology frames the fighting as annihilation, especially in the East. Comparison prompts between the wars reward mobilisation depth, civilian targeting and ideological stakes as the axes, with the Pacific and European wars kept distinct in method and timeline.
The Holocaust is examinable as method and crime
The Holocaust applied industrial organisation, registration, transport, camps, to the murder of six million Jews alongside Roma, disabled people and political prisoners: genocide with a bureaucracy. The exam treats it as mass violence to be analysed, escalation from exclusion to annihilation, and paired in the unit with the century's other mass atrocities, each named rather than generalised.

What does AP World History Unit 7 cover?
1900 to 1945: the First World War and imperial collapse, the failed interwar order, depression and authoritarianism, the Second World War and the Holocaust.
How should I write about the war's causes?
Structure over spark: rank industrial rivalry, alliances and nationalism as the loaded gun, with the assassination as trigger.
What makes both wars total wars?
Whole economies and populations mobilised, with the second going further: home fronts targeted and ideology framing annihilation.
Why do colonial troops matter in this unit?
They made both wars global in fact, and unkept wartime promises to them seeded the interwar and postwar independence movements.
How does the exam frame the Holocaust?
As analysable mass violence: escalation from exclusion to industrial genocide, named precisely alongside the century's other atrocities.
Can I build questions from my own Unit 7 notes?
Yes. Point the camera at the pages or send the PDF, and the questions stay within that material instead of ranging across the term.
