Create Question-by-Question Test-Prep Video Solutions With Golpo

The short answer: A prep company can give every practice question its own polished video solution. Golpo scripts the walkthrough, plans the board, draws the work, narrates it, and syncs the pictures, whether the question comes from the company library or from a learner's screenshot.

Why this is practical now: The video library can be as deep as the question library. Scripting, storyboarding, drawing, voicing, and editing used to take a day per item. Golpo does that production in minutes. A founder, tutor, or YouTuber can appear beside every explanation from one selfie, in a voice students already recognize.

Each video can show why the right answer works and why every other choice fails. One team can build that coverage across a bank, then generate the next approved question from Codex, Claude Code, Cursor, or the Golpo MCP server.

What Golpo does for the prep company

Golpo is built to be the world's best AI whiteboard explainer video maker. Give it a topic, a prompt, a script, an audio recording, or a source document. It scripts, plans the scenes, designs the visuals, narrates, times and synchronizes every frame, and returns a polished video. One person can run that system across a whole course.

Once the checked question record exists, Golpo can take over the production work: draft or accept the exact script, plan the visual sequence, design the whiteboard scenes, narrate in the selected voice, synchronize narration and animation, and return a polished video. That is what makes a question-by-question library practical rather than aspirational.

• Consistent tutor presence. A founder, tutor, or YouTuber can upload a selfie with AI Presenter and appear beside the explanation.
• A recognizable teaching voice. Use Golpo narration, Own Narration, or an authorized Voice Clone.
• Targeted repairs. If review finds one wrong symbol or frame, use the frame-by-frame editor instead of rebuilding good scenes.
• Different visual systems by subject. Algebra can use worked whiteboard steps; reading can keep the passage visible; science can animate the diagram; vocabulary can picture context.
• A library that generates itself. The Golpo API, the Codex skill, the Claude skill, and the Golpo MCP server can produce the next approved question from Cursor, Claude Code, VS Code with GitHub Copilot, Claude Desktop, or Visual Studio.

Two ways a practice question enters the workflow

1. From the company’s question library. The course already stores the question, passage or diagram, answer choices, correct answer, and worked reasoning. An agent can select the next approved record and create its video automatically.
2. From a learner’s screenshot. The learner uploads a screenshot from an allowed practice source. OCR or a vision model transcribes the entire image. Before any explanation is written, a reviewer checks every symbol, word, answer choice, passage line, and diagram label against the screenshot.

Both paths converge on the same checked record. A screenshot is not ready merely because OCR produced text. A missing negative sign, a changed exponent, an omitted “not,” or one truncated answer choice can reverse the lesson.

Example 1: an algebra screenshot with four choices

The screenshot asks: if 3(x − 2) = 15, what is x? The choices are 3, 5, 7, and 17/3.

The verified solution is x = 7. Divide both sides by 3 to get x − 2 = 5, then add 2. But the video should not stop at “C is correct.” It should test every alternative in the original equation:

• A: 3 produces 3, not 15.
• B: 5 produces 9.
• C: 7 produces 15, so it is correct.
• D: 17/3 produces 11. That distractor comes from dropping the parentheses.

That explanation teaches the legal method, validates the result, and diagnoses the misconception behind the strongest wrong option.

Example 2: a screenshot with a full reading passage

A reading question raises a different QA problem: the entire passage matters, not just the final question line.

Choice C is correct because it captures the full chain in the passage: Lena observed that bed depth affected moisture, then changed both construction and watering plans. Each alternative can be rejected from the text:

• A says rooftop gardens cannot survive heat. The passage never says that.
• B says Lena replaced the tomatoes. She did not.
• C connects the observation to the revised plan.
• D says every bed needed the same water, while the passage explicitly describes different needs.

The QA record behind every video

Before Golpo generates anything, store these fields with the question:

• The original screenshot or approved question-library record.
• The checked transcription of the full question, passage, diagrams, and every answer choice.
• The verified correct answer and complete worked solution.
• A reason the correct choice works.
• A separate reason each alternative fails.
• The reviewer, source version, and question version.

One agent drafts the explanation from that record. A separate QA agent solves or reads the question independently. It compares its result with the stored solution and checks every option’s reasoning. A disagreement does not become an improvised prompt revision. It stays unpublished until a tutor or subject expert resolves it.

Two screenshot-based Golpo videos

Both lessons below were generated from the displayed question screenshots. They explain the correct answer and address every alternative.

Own Narration: OFF · Script Mode: ON · Duration: 1 minute · Orientation: Horizontal (16:9) · Style: Dry Erase · Color: ON · Language: English · Voice: Male 1 · Pace: Normal · Music: None

The screenshot asks: if three times the quantity x minus two equals fifteen, what is x? Start from the equation. Divide both sides by three, so x minus two equals five. Add two, and x equals seven. That makes choice C correct. Now check every alternative. Choice A is three. Substitution gives three times one, which is three, not fifteen. Choice B is five. Substitution gives three times three, which is nine. Choice D is seventeen thirds. That answer comes from dropping the parentheses and treating the left side as three x minus two. In the original equation it produces eleven, not fifteen. Choice C produces three times the quantity seven minus two: three times five, exactly fifteen. The correct answer is not just the option that follows the legal steps. It is the only option that satisfies the original equation when substituted back in.

Begin with the uploaded question screenshot shown clearly. Transcribe the equation and all four choices. Solve x minus two equals five, then x equals seven. Test A, B, C, and D in the original equation. Mark C only after all four substitution checks. Allowed labels: 3(x - 2) = 15; A: 3 gives 3; B: 5 gives 9; C: 7 gives 15; D: 17/3 gives 11; Correct: C. Do not add a sample stamp, a demo label, or any claim that the lesson is fictional. Show only the labels listed. If a number appears, it must match the narration exactly. No extra dates, prices, percentages, logos, or quotations.

Patient test-prep tutor. Read each choice distinctly and make the substitution checks easy to follow.

Own Narration: OFF · Script Mode: ON · Duration: 1 minute · Orientation: Horizontal (16:9) · Style: Professional Clean · Color: ON · Language: English · Voice: Female 2 · Pace: Normal · Music: None

The screenshot asks for the main idea. Lena expected rooftop tomatoes to struggle in the heat. She observed that shallow beds dried quickly while deeper beds retained moisture. She then changed both future bed depth and the watering plan. Choice C captures that full chain: bed depth and measured moisture changed the garden plan. Choice A says rooftop gardens cannot survive hot weather. The passage never says that; the tomatoes remain in the plan. Choice B says Lena replaced the tomatoes. She did not. Choice D says every bed needed the same amount of water, but the passage states the opposite: the deepest beds needed no extra water while the shallowest were watered twice. C is correct because it includes the observation and the decision that followed. The other choices contradict or invent details. A strong main-idea answer covers the passage without reaching beyond it.

Begin with the uploaded reading screenshot. Show the full passage before isolating the question and all four choices. Picture shallow and deep rooftop beds retaining different moisture. Compare each option with the passage. End with C as the only choice that includes both the observation and Lena changing the plan. Allowed labels: A: contradicts passage; B: not stated; C: observation changed plan; D: opposite of passage; Correct: C. Do not add a sample stamp, a demo label, or any claim that the lesson is fictional. Show only the labels listed. If a number appears, it must match the narration exactly. No extra dates, prices, percentages, logos, or quotations.

Warm reading tutor. Contrast what the passage says with what each wrong option invents.

Automate the question-to-video library

The Golpo API can run behind a prep platform. Codex with the Golpo Codex Skill, Claude Code with the Golpo Claude Skill, or Cursor, VS Code with GitHub Copilot, Claude Code, Claude Desktop, and Visual Studio through the Golpo MCP server can orchestrate the flow.

1. Receive the approved question record or screenshot.
2. Transcribe the image and compare the transcription with the full screenshot.
3. Independently solve the question and review the reasoning for every choice.
4. Send the approved script and screenshot to Golpo.
5. Transcribe the finished audio.
6. Run two independent LLM reviews of that final transcript against the checked question record.
7. Inspect frames for symbols, diagrams, and answer-choice labels.
8. Publish to the course library only when every gate passes.

What blocks publication

• The screenshot transcription misses any part of the question, passage, diagram, or choices.
• The stored correct answer disagrees with the independent solution.
• The explanation never addresses one or more alternatives.
• A final transcript changes a number, symbol, negation, or answer choice.
• An on-screen frame credits the wrong choice or displays a different equation.
• The course is not permitted to reproduce the source question.
• The video promises a score increase the course has not measured.

FAQ

Can Golpo create a video from a screenshot of a practice question?

Yes. The platform can pass the screenshot to Golpo with an approved script and instructions. First transcribe and verify the complete screenshot so the video is not built from a missing sign, line, or answer choice.

What does “answer key” mean here?

It means the stored correct answer. This workflow also requires the complete worked solution and a reason for every alternative, because a letter by itself cannot support a useful explainer.

Does the video explain why wrong choices are wrong?

Yes. That is part of the required record and both examples do it. A multiple-choice explainer is incomplete if it only announces the correct letter.

Can a prep company automate an entire question bank?

Yes. The API, Codex and Claude skills, or MCP clients can move approved questions through generation, transcript QA, frame QA, and draft publication. Disagreements remain unpublished.

Can learners upload their own screenshots?

Yes, when the platform’s content policy allows it. The screenshot still passes transcription review, solution review, and expert escalation before a video reaches the learner.

Who resolves a disagreement?

A tutor or subject expert. Neither the drafting agent nor Golpo should silently choose between conflicting solutions.

Can the tutor appear in every lesson?

Yes. AI Presenter can use an uploaded selfie, and Own Narration or an authorized Voice Clone can preserve a consistent teaching presence at scale.

Does this workflow guarantee a higher test score?

No. It creates and checks question explanations. A score-impact claim would need separate evidence.
