Turn Your Question Bank Into Paid Online Tests

Last reviewed 7 October 2026

A question bank sitting in documents earns nothing. This page is a practical path from files to published tests, including the rights and quality checks that come first.

Step 1: Check that the questions are yours to sell

Before anything else, confirm that you have the right to use and sell every question. Questions you or your faculty wrote are fine. Questions copied from textbooks, other institutes' papers or past exam papers are not yours to sell, and including them risks complaints and removal. If in doubt, rewrite the question in your own words and numbers, or leave it out.

Step 2: Audit the bank

Take a sample of 50 questions and check:

CheckPass if
Correct keyA second teacher solves it and agrees
Clear wordingNo ambiguity; consistent units
CurrentMatches the exam's current pattern and syllabus
ExplanationExists, or can be written
DifficultySpread of easy, medium and hard

If many questions fail, the bank needs cleaning before it can be sold. See how to build a question bank.

Step 3: Tag and clean

Add tags for exam, subject, chapter, topic, difficulty and type. TestMint organises questions by exam, subject, chapter and topic, and each question has a type (single choice, multiple select, true or false, numerical) with marks and negative marks. Fix duplicates and retire outdated questions.

Step 4: Import

Import from CSV or Excel files, preview them and fix errors before confirming. Do a small batch first to learn the format, then import the rest. Images and rich formatting can be added in the question editor.

Step 5: Write explanations

Explanations are what turn questions into a product. Use the template in how to write good MCQ explanations and prioritise the hard questions.

Step 6: Package into tests and packs

Use a blueprint: topic tests, sectional tests and full-length mocks, as in how to structure a test series. Assemble tests from the bank with the exam's pattern, avoiding repeats within a series. Group them into packs.

Step 7: Publish a free sample and price the rest

Publish a free test of each layer so that students can judge quality, then price the paid tests and packs. Use how institutes should price mock tests for the method. Publishing needs institute approval by the TestMint team; the revenue share and optional plans are on the pricing page. For how sales and payouts work see sell mock tests online and paid online tests.

A worked example

An institute has 3,000 questions in documents. After the audit, 2,400 pass the rights and quality checks (80%). After removing duplicates, 2,000 remain. With 25 questions per sectional and 100 per full mock, 2,000 questions can support, with minimal overlap, about 40 sectionals (1,000 questions) and 10 full mocks (1,000 questions). The numbers are illustrative, but the exercise shows how to size what the bank can support.

Keep it alive

  • Review results to find flawed questions and fix them.
  • Update for pattern changes each year.
  • Add new questions regularly so the series stays fresh.

Frequently asked questions

No. You should sell only questions you or your faculty wrote or otherwise have the right to use. Copying risks complaints and removal.

Audit a sample of 50 questions for correct keys, clear wording, currency, explanations and difficulty. If many fail, clean the bank first.

Yes, from CSV or Excel files, with a preview and error fixing before you confirm. Start with a small batch.

Tags for subject, chapter and topic, correct types, marks and negative marks and, importantly, explanations.

Plan a blueprint of topic, sectional and full-length tests, assemble each from the bank with the exam's pattern and avoid repeats within a series.

Yes. A free sample of each layer lets students judge quality before buying.

Size it from the questions that pass your audit and the questions per test. For example, 2,000 good questions can support about 40 sectionals of 25 and 10 full mocks of 100 with little overlap.

Students pay through checkout, earnings are recorded in your ledger and the TestMint team processes payouts. The share and plans are on the pricing page.

Yes. Institutes are reviewed by the TestMint team before they can publish, while you can build the bank in the meantime.
