Adaptive questions

The same idea, asked a new way

Memorising an answer is not the same as understanding it. When you get a question right twice in a row, BrightStudy writes a fresh version that tests the same learning target with a new scenario, new data and new wrong options.

Why it matters

Recognising an answer is not knowing it

See the same question often enough and you start to remember the answer, not the reason. Adaptive questions stop that: once you have shown you know a question, it changes.

01

Same learning target

Every version tests the same idea, with the same four tags.

02

New scenario and data

The evidence, numbers or case change, so you have to reason it through again.

03

New wrong options

Fresh distractors, each with its own explanation.

04

The answer moves

The correct option lands in a different position.

05

Reviewed before it appears

Each new version is checked before it goes live, like every other question.

One idea, three versions

Watch a question evolve

Here is how one learning target could look across three versions. The idea stays put; the way it is asked does not.

Stays the same

Learning targetTopicConceptDifficulty

Learning target

Explain how the length of the loop of Henle affects how concentrated urine can be.

Pick a version

Version 1

  • A desert mammal produces very concentrated urine. Which feature of its kidneys best explains this?
  • Answer: a longer loop of Henle relative to kidney size.

Version 2

  • Two species have the same body mass. Species P has loops of Henle twice as long as species Q. What would you expect of species P’s urine?
  • Answer: it can be more concentrated, because a steeper medullary gradient draws out more water.

Version 3

  • A drug shortens the effective length of the loop of Henle. Which change in urine would you predict?
  • Answer: larger volumes of more dilute urine, because the medullary gradient is weaker.
How it works

Earn the next version in four steps

It happens in the background while you practise, so the next time the question comes round it is new.

Answer correctly

Get the current version right.

Do it again

Two correct answers in a row complete a version. A wrong answer resets the count.

A new version is written

Same learning target and tags, new scenario, data, wrong options and answer position.

  • Not just reworded
  • Difficulty never jumps because of a streak

Brain number goes up

The question’s brain badge counts the versions you have worked through.

What changes

More than a rewording

A rename or a reshuffle is not enough. Each new version has to make you think again.

Change 1

The scenario

A new case, context or example.

From a desert mammal to two species compared side by side.

Change 2

The data

New numbers, results or evidence to read.

Loops “twice as long” instead of a description.

Change 3

The direction

Reason forwards, backwards or predict an effect.

From “explain what you see” to “predict what happens”.

Change 4

The wrong options

Fresh distractors, each explained.

New tempting mistakes, so you cannot pass by elimination.

See the difference

Measure understanding, not memory

Progress tracks how you do the first time you meet a new version, which is a far better test of understanding than answering a familiar question again.

FAQ

When does a question change?
After you answer the current version correctly twice in a row. A wrong answer resets the count, so a new version always means you knew the last one.
Does the question get harder?
No. The difficulty and scope stay the same on purpose. The new version tests the same learning target in a different way, so you cannot rely on remembering the old answer.
What stays the same between versions?
The learning target and the question’s four tags: topic, knowledge type, concept and micro tag. The scenario, data, wrong options and answer position change.
What is the brain number?
A badge on each question that counts its versions. It starts at 1 and goes up each time you earn a new version.
Can I stop a question from changing?
Yes. Each question has a regeneration control in the practice session: on, repeat until correct, or paused.
Is every new version checked?
Yes. New versions go through the same review as all BrightStudy questions before they appear. If a worthwhile new version cannot be written, the current one stays.
Which plans include adaptive questions?
MCQ regeneration is included on the Pro and Max plans. Compare plans.
