Frequently asked questions
Everything you need to know to start practicing.
Is the Exam Simulator free?
Yes. You can use every feature without paying. The site is supported by ads.
Do I need an account?
No. There's no sign-up or login. Just open the page and start using it.
Where are my banks and results stored?
In your browser's local storage, on your own device. We don't receive them or store them on any server. That's why it's a good idea to export your banks before clearing your browser data or switching devices.
Which AIs can I use?
With the copy-and-paste option, any AI that accepts files works, such as ChatGPT, Gemini, Copilot or Claude, even their free versions. With the automatic option you can connect Gemini, OpenRouter or any OpenAI-compatible service using your own key.
Can I try it without my own questions?
Yes. On the home screen there's a Try a sample bank button with general-knowledge questions so you can see how exams work.
Does it work offline?
Studying and loading banks works offline once the page has loaded. Reading PDFs needs internet the first time to download the reader, and the automatic option needs a connection to talk to the AI.
How do lives work in exams?
Each exam starts with 3 lives. Each wrong answer costs one, and if you lose them all the exam ends; questions you didn't get to count as wrong. Practice mode has no lives and shows the explanation for each answer.
What does "Sentence not found in the PDF" mean?
Every AI-made question includes the sentence from the material that supports it. If you load your PDFs, the simulator searches for that sentence; if it isn't found, the AI may have made it up, or it may come from an image or table. Review those questions before saving.
How do I share a bank with classmates?
Open the bank and use Share bank (.json). A file is downloaded that you can send via WhatsApp, email or Drive. Your classmates load it with Load a bank someone shared with me.
Can I use it on my phone?
Yes. The site works in any modern browser on phones, tablets and computers.
How do I change the language?
Use the ES | EN switch at the top of any page.
How do I delete all my data?
From each bank you can delete it or clear its statistics. To erase everything, clear this site's data in your browser settings.
