Check any practice test and learn why each answer is right
A practice test that came with no answer key gets marked question by question, with the why behind each answer.
Published . Steps as of October 2026.
How can I check my practice test answers if there's no answer key?
Attach photos or a PDF of your filled-in practice test to Gemini, ChatGPT or Claude and ask it to mark each answer and explain why. Any of the three can read the pages and explain the reasoning. For a licensing or certification test, ask it to flag anything it isn't sure of and check that against the official handbook. For school study, ask for new questions on your weakest topic so you practice the part you missed.

ChatGPT and Claude open with your prompt already typed in. Gemini can't be filled in from a link, so its button copies your prompt: paste it into the new chat.
The prompt that gets copied
I'm studying for [THE TEST, e.g. my state driver's permit test]. I've attached a practice test with my answers marked, and it didn't come with an answer key. For each question, tell me whether my answer is right or wrong, give the correct answer, and explain the reasoning in two or three plain sentences, like a patient teacher. If a question is ambiguous or you aren't sure, say so and tell me where I can check the official answer. Then group my wrong answers by topic, tell me which topic to study first, and write 3 new practice questions on it. Put those answers at the very end so I can try them first.
Photograph a practice test you've filled in, even one with no answer key, and get every answer marked with the reasoning, your weak topic named and fresh questions on it.
Step by step
- Fill in the practice test on paper or screen
- Take clear photos of each page, or save it as a PDF
- Attach the pages in Gemini and paste the prompt
- Try the three new questions before you read the answers
What you'll get
Every question marked right or wrong with a short explanation, your weakest topic named, and three new practice questions with answers at the end.
