CastIQ AI Question Paper Solver: Step-by-Step Solutions to Any Exam Paper
How CastIQ's Solver reads an uploaded question paper and works through every question step by step — question types, math support, and its real limitations.
On this page
CastIQ's Solver reads an uploaded question paper — a PDF or a photo — and works through every question step by step, including numerical and math questions with full working, not just the final answer.
A practice paper is only useful once you know which answers were right, and — more importantly — where a wrong answer actually went wrong. Checking a full paper by hand against an answer key, or retyping each question into a chatbot one at a time, is slow enough that most people just skip it.
What the solver actually handles
- Seven question types — multiple choice, true/false, fill-in-the-blank, short answer, long answer, numerical, and match-the-following.
- Full step-by-step working for numerical and math questions, not just a final number.
- Proper math rendering for formulas, so a physics or chemistry solution is actually readable.
- Works from a photo or a PDF of a printed or handwritten paper.
How it's different from asking a general chatbot
A general-purpose AI chatbot can solve a single question if you type or paste it in — but a full paper means doing that once per question, and formatting each one correctly yourself. CastIQ's solver processes the whole paper in one upload and returns solutions matched back to each numbered question, so the output mirrors the paper you started with instead of a loose chat thread.
Scan quality matters
Accuracy depends heavily on how legible the source is. A clean PDF or a well-lit, in-focus photo gives the most reliable results — blurry handwriting or a heavily skewed photo increases the chance of a misread question. For anything high-stakes, treat the solutions as a strong first pass and verify against your own understanding or a teacher, the same way you'd check any answer key.
Stuck on a practice paper with no answer key?
Try the AI Solver →How to use CastIQ's question paper solver
- 01
Upload the question paper
A PDF or a photo of a printed or handwritten paper both work.
- 02
CastIQ detects each question
Questions are identified and numbered automatically, matching the original paper.
- 03
Get step-by-step solutions
Each question is worked through individually, including full working for numerical questions — not just a final answer.
- 04
Ask a follow-up
If a step doesn't make sense, ask the AI Tutor to explain that specific part further.
Once you know which topics you got wrong, it's usually faster to go generate fresh notes on that specific topic than to keep re-attempting the same paper — and once you're confident again, a quiz on that topic confirms it actually stuck.
Frequently asked questions
Multiple choice, true/false, fill-in-the-blank, short answer, long answer, numerical (calculation-based), and match-the-following questions.
