Our academic integrity stance.

Our position

Curve exists to help you learn AP material, not to help you fake the work. We’ve watched the entire “AP answer key” ecosystem fill up with copy-paste sites that don’t actually explain anything — they just farm SEO traffic from desperate students.

That’s not a good business to be in, and it’s not a good way to actually pass an AP exam in May. So we made a different bet: explain reasoning, surface common mistakes, and trust students to use that as study material, not as a workaround.

Walkthroughs vs. answer keys

Here’s the difference, with a concrete example.

An “answer key” site says: AP Calc AB Progress Check Unit 3 Question 12 = B.

A Curve walkthrough says: Unit 3 tests composite functions and the chain rule. The most common Question 12-style trap is forgetting the “inner” function when differentiating f(g(x)). The correct approach: write f'(g(x)) · g'(x) explicitly before plugging in. If you skip that step, every chain-rule MCQ becomes a coin flip.

Same topic. Totally different ROI for the student. The answer-key approach gets you through tonight’s homework and a 1 on the exam. The walkthrough approach takes ten more minutes per question and gets you a 4 or 5 in May.

When using Curve is fine

• You’re studying on your own time. Read walkthroughs, do the Progress Check, check your reasoning against ours. Repeat until you can explain a concept without looking.
• You’ve already submitted an assignment. Use Curve to figure out where you went wrong. This is exactly what walkthroughs are for.
• You’re using the calculator to estimate your score. There’s no integrity dimension here; it’s a math tool.
• You’re using the writing tools on your own drafts to clean up clichés and check word count. Same.

When it isn’t

• Copying walkthrough text into an AP Classroom FRQ box during the assignment. Even if the explanation is in your own words after rewriting, the time-on-task and paste detection still flags you. And you didn’t learn anything.
• Submitting Curve’s example responses as your own work for a graded assignment. Same logic.
• Bringing any printed Curve material into the actual AP exam room. Outside materials are prohibited.
• Sharing your school’s AP Classroom prompts with us to ask us to write the answer. We won’t, and we’ll flag the request.

What AP Classroom tracks

Many students don’t realize how much telemetry AP Classroom collects. Here’s the public-record list:

• Time on task — seconds spent in each question and the assignment overall.
• Paste detection — whether content was typed vs. pasted into a free-response box. Teachers see a flag.
• Window focus — whether you switched browser tabs during the assignment.
• Per-question accuracy + skill-level breakdown — your teacher sees a heatmap of weak topics.

If your time-on-task is two minutes for a 25-question Progress Check, no teacher is going to assume you understood it.

Consequences if you cross the line

Consequences depend on your school’s policy, not the College Board’s. Progress Checks aren’t part of the AP exam score — they’re locally graded.

That said, most schools treat a paste-flagged FRQ the same as any other plagiarism: zero on the assignment, a meeting with the dean, possibly a notation in your file. If it happens during the actual AP exam, the College Board cancels the score and your school is notified.

None of this is meant as a scare tactic. The point is: the system is more observant than you assume. Use Curve as a study tool, on your own time, and you have nothing to worry about.
