Past papers in.
Ready-made exams out.
A desktop app that turns your past papers and mark schemes into a question bank, then builds new exams with matching mark schemes in seconds. Ask for what you want in plain words, and get the exact marks you asked for.
Works with Cambridge International and Pearson Edexcel past papers: IGCSE, International GCSE, AS and A Level. See what's been tested
From a folder of PDFs
to a finished exam
Add papers once. Every exam after that takes a sentence.
Add your papers
Choose a question paper and its own mark scheme. The app checks they belong together, then finds every question and part, its marks and its mark scheme answer.
Check the results
Anything that doesn't add up is listed with the reason, so a clean paper takes one keystroke to approve. AI can suggest fixes, and every fix is checked again before it's used.
Build exams
Type what you need, or pick questions by hand. You get a question paper and a mark scheme as PDFs, laid out like the originals.
Every question you own,
findable in seconds
Each question part is cut out of the paper as it was printed, with its diagrams, tables and formulas, and linked to its row in the mark scheme. Search by wording, or filter by subject, paper, year and syllabus topic.
- Questions kept exactly as printed, never retyped
- Each part linked to its mark scheme answer
- Tagged with topics from your syllabus
- Filter by subject, paper, year, topic and style
Say what you need.
Get the exact paper.
Describe the exam in your own words. AI reads your request, then the app picks the questions, so the marks always add up exactly and you can run the same request again for a different set.
- Requests in plain words, like you'd tell a colleague
- Exact mark totals, with the mix of question styles you ask for
- Change an exam in words: swap a question, cut the total
- Try different questions with one click
Every past question on a topic,
in one booklet
Pick the subject, papers, years and topics. Each topic gets its own booklet of past questions with its mark scheme, downloaded together.
- One booklet and mark scheme per topic
- Choose the years, papers and question style
- Download them all at once
Built for teachers who
write a lot of exams
Everything below comes with every subscription.
No repeated questions
Questions reprinted across papers, and questions with the same answer, never appear twice in one exam.
New questions first
Exams the AI builds don't reuse questions already in your other saved exams.
Linked parts kept together
A part that needs an earlier answer, table or diagram brings that part with it.
Real mark schemes
Mark scheme rows are copied from the original, so codes, subscripts and formatting stay intact.
Recent years preferred
Newer papers are favoured, without always picking the same questions.
Build by hand too
Pick questions yourself from the bank. Manual mode needs no AI at all.
A fast reviewer
Question paper and mark scheme side by side, keyboard shortcuts, and a list of only what needs a look.
Your name on the paper
Add your own note to the footer of every page you print.
Your papers stay with you
PDFs and exams are kept on your computer. AI features send question text only, never your files.
Good to know
Do I need a Classark course plan?
No. Exam Builder is its own subscription. You sign in with a Classark account, which can have a course plan, Exam Builder, or both.
Does it come with past papers?
No. The app contains no exam content. You add the question papers and mark schemes you already have, and they stay on your computer.
Which exam papers can it read?
Cambridge International and Pearson Edexcel past papers and mark schemes: IGCSE, International GCSE, AS and A Level. See what's been tested
What does the AI do, and what does it cost?
AI tags questions with syllabus topics, reads your exam requests and suggests fixes to the extraction. It never writes or rewrites questions. Each month includes $5 of AI usage, which doesn't carry over. If you need more, you can buy top-up credit.
What happens if my AI usage runs out?
Everything else keeps working: your question bank, building exams by hand, booklets and PDFs. AI features come back when your allowance refills or when you add credit.
What do I need to run it?
A Windows PC or a Mac (there's no Linux version), and an internet connection to sign in and use the AI features. Your papers and exams are stored on the computer itself, so back up its data folder as you would any other files. See the system requirements
How do I cancel?
From your Exam Builder page, open billing and cancel. You keep access until the end of the period you've paid for. After that, any AI usage you have left (this month's allowance and top-up credit) stays usable until it runs out.
