Every invigilator knows the glance. A student finishes question 14, looks up, and their eyes drift half a metre to the left. In an MCQ exam that glance is worth a whole answer, because copying an answer means copying one letter.

The board exams solve this with different sets — Set A, B, C and D — so the person next to you has the same questions in a different order with the options moved around. Schools and coaching centres rarely do it, for one reason: making four versions of a paper, four answer keys and four piles of marking by hand is miserable. ScanScore makes it one switch.

Why copying is so easy in MCQ halls

  • Answers are tiny. One letter or one filled bubble can be read from a seat away.
  • Halls are crowded. Most classrooms cannot seat students a metre and a half apart.
  • Invigilators are stretched. One teacher, forty students, ninety minutes.
  • The cost is invisible. Copied marks look like real marks, so the analytics lie too.

That last point matters more than it seems. When answers are copied, your class analysis tells you a topic was understood when it was not, and you skip re-teaching it.

What changes between sets

Turn on multi-set and ScanScore deals out up to four sets from one paper:

  • Set A stays exactly as you wrote it — so your master copy, your discussion notes and any printed reference still match one set precisely.
  • Sets B, C and D shuffle the question order, within each section, so a Physics question never lands in the Chemistry section.
  • The options are shuffled too, and each question’s correct answer moves with it. The right answer to the same question might be B in Set A and D in Set C.
  • Questions built on a passage or table stay together, so a comprehension block is never split up.
  • Options like “all of the above” stay in place. An option that refers to the others by position stops making sense if it moves, so ScanScore pins it.
Why both kinds of shuffle matter: shuffling only the questions still lets a student match a recognisable question and copy its letter. Shuffling only the options leaves the same question at the same number. Doing both means a glance at a neighbour’s sheet tells you nothing useful.

Making Set A to D

01

Start with the paper

Use the question paper editor in the ScanScore Android app. Write the questions yourself, bring in an existing paper from a PDF or photos, or let the MCQ generator write one. Only the AI writing uses credits.

02

Switch on multi-set

Choose how many sets — two, three or four — and whether to shuffle questions, options, or both.

03

Export and print

You get one question paper file per set, its own OMR sheet and answer key, and a master key showing where every question went in every set.

The shuffle is remembered. If you need twenty more copies of Set C next week, the reprint matches the copies already handed out, question for question.

Exam day: handing out sets

  • Alternate by seat — A, B, A, B along a row, and C, D, C, D in the row behind — so no two neighbours, side to side or front to back, share a set.
  • Keep each set’s sheets with its papers. Each set has its own OMR sheet, so hand them out together.
  • Collect by set — four piles. It makes scanning straightforward.

Marking four sets without four times the work

Each set is saved as its own exam, with its own answer key. Open the Set B exam, scan the Set B pile, and every sheet is marked against Set B’s key — no mental conversion, no risk of marking a Set C student against Set A’s answers. Scanning is free and unlimited, so four sets cost you exactly what one did: a few minutes per class.

Your marking rules come along too: marks per question, negative marking as ¼ or ⅓, and decimal scores all carry across to every set. See the negative marking guide for the schemes.

Going over the answers in class

The awkward part of sets used to be the discussion: “question 12 in Set A is question 31 in Set C”. The master key solves that. It lists every question with its position and correct option in each set, so you can teach from Set A and any student can find their own version instantly.

What multi-set does not do

  • It is in the Android app only. The question paper writer works in the browser too, but making sets needs the app.
  • Four sets at most. In a crowded hall, four sets arranged in a grid is enough to make sure no neighbour shares yours.
  • It does not replace invigilation. It removes the easiest form of copying; phones and notes in pockets are still the invigilator’s job.

If copying has made you distrust your own MCQ results, this is the cheapest fix there is. Make one paper, switch on four sets, and the glance to the left stops being worth anything.
