Most teachers don’t choose a question bank so much as drift into one — whatever came bundled with a textbook, whatever a colleague mentioned, whatever a free site turned up first. Then you hit the wall mid-term: you want six “explain” questions on a single sub-topic, at two difficulty levels, with the mark scheme attached, and the bank simply doesn’t hold that shape of question. So you fall back to scanning PDFs of past papers by hand.

The problem is rarely the number of questions. It’s coverage. A bank can be huge and still be missing the formats, the boards, or the tagging you actually need on a Tuesday night. This is a criteria guide to what a question bank should cover — a checklist you can hold any teacher question bank up against before you build a term’s worth of tests and homework on top of it. The single most important line on that checklist: is it a question bank covering every question format your students will actually meet in the exam?

Why “every question format” is the real test

An IGCSE or A-Level paper is not one kind of question. It’s a deliberate spread — recall, application, analysis, evaluation — and each tier is assessed through a different format. A bank that only holds multiple-choice questions trains recall and nothing above it. A bank of only extended essays is useless for a quick five-minute recall check. If your bank can’t supply the format that matches the skill you’re assessing, you end up assessing whatever the bank happens to contain, not what you meant to teach.

So the first criterion isn’t size. It’s whether one bank, in one place, gives you the full range below — without forcing you to keep three other sources open.

The format checklist: what complete coverage looks like

Run any question bank against these six formats. A bank covering every question format will give you all of them, tagged and mark-scheme-ready, in the same search:

• Multiple-choice (MCQ). Fast recall and misconception checks. The mark of a good MCQ set isn’t volume — it’s distractors built around the specific errors students make, so a wrong answer tells you which misconception to reteach.
• Short-answer. One- to three-mark questions that test a single point of knowledge or a defined term. These are the backbone of low-stakes weekly checks and the easiest to auto-mark cleanly.
• Structured questions. Multi-part questions that scaffold from “state” to “explain” to “calculate” within one stem. This is the dominant IGCSE format, and a bank that’s thin here is thin where it matters most.
• Data- and source-response. Questions built on a graph, table, table of results, map, or source extract. Common in sciences, geography, economics, business and history — and frequently the first thing a weak bank drops, because the stimulus material is harder to digitise.
• Extended / essay response. The high-tariff “discuss”, “evaluate”, “to what extent” answers that separate grades at the top end. Your bank needs these with the levelled mark scheme, or you can’t mark them consistently.
• Method / working questions. In maths and the sciences, the marks live in the working, not just the final answer. A bank that only stores the answer can’t credit method marks — so check it carries the full mark-scheme breakdown for calculations.

If a bank gives you four of these six, you’ll keep a textbook and a PDF folder open alongside it forever. The whole point of asking what a question bank should cover is to stop juggling sources.

Beyond format: the coverage criteria that decide a bank’s value

Format is the spine, but a complete bank has to be wide on several other axes too. Hold your candidate up against each.

1. Both boards, both levels

You teach Cambridge or Edexcel — and across a department or a tutoring caseload, often both, and across IGCSE and A-Level. A bank that only holds Cambridge IGCSE leaves you stranded the moment you pick up an Edexcel group or a sixth-form class. Coverage across Cambridge and Edexcel, IGCSE and A-Level is non-negotiable if you want one tool instead of four.

2. Topic and sub-topic tagging

The difference between “Biology questions” and “questions on water potential” is the difference between a usable bank and a glorified PDF. Real coverage means every question is tagged down to the sub-topic, so you can drill the exact thing your last lesson exposed. Without sub-topic tagging, every format in the world won’t save you from scrolling. (The mechanics of pulling by topic are covered in assigning past-paper questions by topic and difficulty.)

3. Difficulty tagging

Differentiation lives here. To set a stretch group a harder set and a struggling group an accessible one — on the same sub-topic, without rewriting anything — the bank has to tag questions by difficulty. A bank with no difficulty layer forces you to read every question to gauge its level, which defeats the purpose.

4. Command-word coverage

Boards assess through command words — state, describe, explain, calculate, evaluate, justify — and each demands a different answer and a different mark scheme. A bank worth its name lets you filter by command word, so when your class can’t handle “explain” questions specifically, you can pull a set of exactly those. This is also how you teach students to read what a question is actually asking.

5. Mark schemes attached to every question

This is the criterion that separates a question bank from a question list. Without the mark scheme, you mark by hand and nothing can auto-mark. With the official mark scheme attached to each question — including levelled descriptors for extended answers and method marks for calculations — the bank can mark objective and point-based work instantly, and give you the rubric for the high-tariff answers you review yourself.

6. Breadth across subjects

A bank that’s excellent in Physics and empty in Economics solves one teacher’s problem and no one else’s. For a department, or for a tutor teaching across subjects, coverage means the same format depth and tagging across every subject you teach — so you learn one tool, not one tool per subject.

A quick self-audit you can run in five minutes

Open your current bank and try to do this, end to end:

1. Filter to Edexcel IGCSE Chemistry, one sub-topic.
2. Pull four “explain” questions at two difficulty levels.
3. Add one data-response question and one extended question on the same sub-topic.
4. Check that every one carries its mark scheme.

If you can do all four in a few minutes, your bank has real coverage. If you stall at step two because there’s no command-word filter, or at step three because the data-response questions simply aren’t there, you’ve found the gap — and you now know exactly what to look for in a better one.

The honest caveats

Coverage is necessary, not sufficient. A few things worth keeping straight:

• Breadth without quality is noise. Ten thousand low-quality MCQs aren’t coverage. The questions have to be real past-paper questions with official mark schemes, not approximations someone wrote to pad a count.
• Auto-marking still needs your eyes on the extended answers. A bank can mark short-answer and MCQ cleanly; the levelled “evaluate” responses want a human review against the rubric. Coverage gives you the rubric — it doesn’t remove your judgement.
• More formats doesn’t mean every test uses all of them. A good bank lets you choose the right format for the job. The balance between, say, MCQ and structured questions is a separate design decision — there’s a full treatment in structured vs MCQ for balanced A-Level assessment.

How this looks in practice

If you want a bank that meets the full checklist, Tutopiya’s platform for teachers is built on real Cambridge and Edexcel past-paper questions covering every format — MCQ, short-answer, structured, data-response and extended — across 26 IGCSE and A-Level subjects, tagged by topic, sub-topic, difficulty and command word, with the mark scheme attached to every question for instant auto-marking. It’s free to create an account, which is enough to run the five-minute self-audit above against your own subject and see whether the coverage holds. Once the bank’s in place, the next questions are how to turn it into homework and how to build exam-board-aligned tests from it.

FAQ

What should a teacher question bank cover, at minimum? Every question format your students will meet in the exam — MCQ, short-answer, structured, data/source-response, extended/essay and method/working questions — across both Cambridge and Edexcel, at IGCSE and A-Level, with tagging by topic, sub-topic, difficulty and command word, and the official mark scheme attached to every question.

Why does a question bank covering every question format matter more than the total number of questions? Because each format assesses a different skill. A bank of only MCQs trains recall and nothing higher; a bank of only essays can’t run a quick check. If your bank can’t supply the format that matches the skill you’re teaching, you end up assessing whatever it happens to contain rather than what you intended.

What’s the difference between a question bank and a folder of past papers? Tagging and mark schemes. A folder of PDFs makes you scroll and mark by hand. A real question bank lets you filter to a sub-topic, difficulty and command word in seconds, and carries the mark scheme on each question so objective work can auto-mark itself.

Does the bank need to cover both Cambridge and Edexcel? If you ever teach across boards — or across a department or tutoring caseload that does — yes. Single-board coverage means a second tool the moment you pick up an Edexcel or Cambridge group, which is exactly the juggling a good bank is supposed to end.

Are the high-tariff extended questions auto-marked too? Short-answer and MCQ mark cleanly and instantly. Extended “evaluate” and “discuss” answers come with a levelled mark scheme attached, so you review them against the official rubric rather than from scratch — faster and more consistent, but still a human pass.

The bottom line

The right way to choose a teacher question bank isn’t to count questions — it’s to check coverage. Run it against the format checklist: can it give you MCQ through extended response, across both boards and both levels, tagged down to sub-topic, difficulty and command word, with a mark scheme on every question? A bank that clears that bar replaces the textbook, the PDF folder and the marking pile at once. A bank that doesn’t will keep sending you back to them, no matter how big the number on the box.
