Would you jump at the thought of being tested on something you haven’t learned yet? No lessons, no notes, and zero preparation of any kind. You would have to sit with questions you struggle to answer.
Doesn’t that sound like a perfect recipe for failure? Perhaps that’s because students are conventionally taught to study first and take tests later. A 2025 meta-analysis found a positive learning effect on information covered by prequestions.
This means the findings suggest that attempting questions beforehand can help learners retain the specific information they subsequently encounter. Counterintuitive as it may seem, this approach is known as pretesting.
This article will take a deep dive into the science of pretesting, exploring how getting it wrong may help you get it right.
How an Incorrect Answer Can Open the Door to Learning
Before we even begin, consider trying a small experiment. Do not look up answers or worry too much about getting them right. All you need to do here is make your best guesses.
A Three-Question Pretest
No studying. No preparation. Just give it a go!
What is the primary source of the mass that a plant gains as it grows?
- Minerals absorbed from the soil
- Carbon dioxide from the air
- Water absorbed through its roots
What causes the seasons on Earth?
- Earth’s changing distance from the Sun
- The tilt of the Earth’s axis
- Changes in the Sun’s temperature
Why does a metal spoon feel colder than a wooden spoon in the same room?
- The metal is actually colder
- Metal conducts heat away from your hand faster
- Wooden products heat up when touched
What Did You Notice?
The answers to the above are as follows:
- Carbon dioxide from the air
- The tilt of the Earth’s axis
- Metal conducts heat away from your hand faster
Perhaps you got all three answers correct. Perhaps one or two surprised you. It’s also possible that you were confident about an answer only to find out that it’s incorrect.
Whatever the result, the important part of this exercise was not the score. It was that you tried retrieving information from your mental reserves before encountering its explanation.
That’s what the unusual premise of pretesting is all about. You do not need to know an answer to attempt the question.
This isn’t just a fascinating classroom experiment. A 2025 study investigated the effects of testing before and after learning across three experiments. The researchers found that testing-based approaches improved memory compared to simply copying information.
In a third experiment involving older adults, pretesting still won over copying information. Interestingly, in all cases, participants underestimated this testing strategy. It makes sense since pretesting challenges the common assumption about learning that time spent looking at/copying information is productive.
Pretesting reverses that sequence, but it isn’t meant to judge your intelligence. In fact, the main goal is to give your mind something concrete to look for when the lesson truly begins.
What the Mind Does in the Space Between a Wrong Guess and a Correct Answer
Contrary to what we may think, an incorrect answer does not simply vanish into thin air when the right answer appears. It can change the way a learner processes the explanation that follows. You can think of pretesting as a sequence of three mental events, as follows:
The Question Provides the Mind Something Related to Look For
Any time we come across an unfamiliar question, our mind naturally tries to recollect whatever related information it already possesses. Even an unsuccessful attempt can activate relevant memories and establish a mental reference point.
This becomes especially useful while approaching specialized academic subjects. For instance, a student pursuing a communication disorders online degree might encounter questions about how children acquire language or how speech differs from language before starting a lesson. Although the student may not know the answers, an attempt to reason through these questions can create specific concepts to look for later.
Essentially, they can explore specific, in-demand areas. Elmhurst University names some of these, including language and voice disorders, dysphagia (swallowing difficulties), motor speech disorders, and alternative communication methods. Each introduces its own terminology, processes, and clinical concepts.
Moreover, the online format of study can accommodate this process within independent study. Students can attempt preliminary questions before opening digital lectures and return to the original questions after completing a lesson. This is anything but a passive learning process. After all, learning is primarily about recognizing which information matters.
Curiosity Makes it Nearly Impossible to Overlook the Correct Answer
Suppose you made a fairly confident guess that the change in Earth’s seasons was due to the planet moving closer or farther away from the Sun. When you later discover that the tilt in the Earth’s axis is responsible, the correction addresses a question you have already attempted.
As a result, the moment of discovery can leave a more pronounced impression. It is known as an attention-based account of pretesting. This means that you attempt an answer before learning even begins; it increases curiosity and encourages you to devote more attention to the correct answer.
According to a 2025 study, pretesting’s benefits disappeared when participants’ attention was divided during the stage in which the feedback for the correct answer was given. So, what requires conscious effort is the explanation part. Do not let complacency (in case of a correct answer) or disappointment (in case of a wrong one) keep your mind from understanding why the answer is what it is.
The Correction Acts as a Valuable Future Reference Point
This is another very interesting possibility. The initial question and its attempted answer may create a mental connection pathway that makes it easier to retrieve information later. For example, a student who originally confused two scientific concepts may remember the question that exposed their confusion when encountering the correct explanation.
The new information now has a context instead of being another isolated fact in a lengthy lesson. Researchers have proposed several explanations for this process, including attention, elaboration, and the activation of related memory representations. Although the exact contribution of each mechanism is still being studied, the takeaway is that an unsuccessful attempt can also influence subsequent learning.
This is not to imply that pretesting makes mistakes valuable simply for the sake of it. Its potential lies in what would follow. So, the learner, being faced with the correct information to an existing or familiar question, has a solid reason to pay attention.
How to Build a Pretesting Routine for Any Subject
There is no requirement for a question paper or a set of flashcards to try pretesting. Even a chapter title can provide you with enough material to get started. The idea is to pause before studying and turn what you are about to learn into a few thoughtful questions.
The questions will encourage you to predict, explain, and compare something related to the subject. The best part? You need not know the answers beforehand because uncertainty is part of the exercise. Now, the questions will look different depending on what you are studying. So, consider how you might approach the following four learning situations:
| Learning situation | A question to attempt before studying |
| Science | What might happen to a plant that receives sunlight but not water? |
| History | What economic or political conditions might lead to a revolution? |
| Language learning | Can you guess the meaning of an unfamiliar word from its context? |
| Professional education | What distinguishes constructive feedback from criticism in a workplace? |
Although all the above-mentioned questions are related to the subject, none of them require learners to know an entire chapter in advance. The same logic can help with a better understanding of complex concepts. For instance, before studying the nervous system, a student can try to explain how the brain communicates with the rest of the body.
Similarly, before a history lesson, they might attempt to arrange a few events in chronological order. Any initial try will allow the mind to have some prior context before the lesson truly begins.
An Easy Five-Step Routine to Follow
The first thing you need to do is to identify a topic for the pretesting technique. Then, follow this simple five-step routine:
- Preview the lesson, which would include reading its title, learning objectives, or even the introductory paragraph to understand what you are about to study.
- Turn the important headings or concepts into three or five questions. Ensure this includes a mix of prediction, explanation, and recall prompts.
- Now attempt an answer without looking it up. Give it your best guess and mark questions you cannot answer to understand your knowledge gaps.
- Study with those questions in mind, working through the explanations and details. Check your guesses against the information presented.
- Once done, answer the original questions again without looking at your notes. Correct any misunderstandings and note what you learned that you had not before.
This process does not require a lot of time. In a recent Associated Press article on effective study strategies, Pooja K. Agarwal, a cognitive psychologist, explained that retrieval practice often takes only a minute or two.
She also emphasized the value of the mental effort involved in the following words: “Engaging in that mental struggle, that desirable difficulty, helps with long-term learning. It’s one of the most powerful learning and teaching strategies based on plenty of research, both in the laboratory and in the classroom.”
Moreover, there is immense value in returning to the study material after some time has passed. Spacing study sessions improves long-term learning compared to concentrating all efforts into a single cramming session. Experiment with the routine a bit and adapt it based on your study material. Over time, this simple habit will change the way you approach a new subject.
Making Mistakes: When It Helps vs. When It Doesn’t
Does every guess or mistake made while pretesting lead to a better understanding of the subject? Not necessarily, because it depends on what learners are asked and whether they can engage meaningfully with the correct explanation.
Take the example of a question or lesson that is too difficult to approach. Learners may find little to connect to the information that follows. Similarly, repeated guessing without checking the correct answers will only lead to more misconceptions. While pretesting can be considered a good place to start, it is not a substitute for instruction, feedback, or independent study.
Furthermore, there is the question of whether this technique works equally well for everybody. A 2026 research perspective examined trends in testing-effect research and its application to learners with specific learning disabilities. The authors identified 204 research items connecting these two areas, but only eight were original experimental studies that directly tested active retrieval against passive understanding.
All eight of them involved learners with developmental language disorder; none examined learners with dyslexia, dyscalculia, or dysgraphia. This doesn’t mean that retrieval-based strategies are ineffective in those learners. It does expose a gap in the available evidence. What’s important to keep in the back of one’s mind is that a certain study technique may not apply universally.
A checklist to help you use pretesting effectively
Before you incorporate this technique into your next study session, work through this checklist first:
- Focus on concepts that will appear in the lesson rather than unrelated or overly broad topics.
- Begin with basic facts, concepts, or predictions that you can reasonably attempt using existing knowledge.
- Record your best guess or acknowledge when you do not know the answer.
- Read, listen to, or watch the relevant material carefully so that incorrect assumptions can be rectified.
- Adjust the difficulty level of the question and consider different formats, such as spoken responses, diagrams, or written answers.
- Answer the questions again after studying and check whether you can now explain the correct reasoning.
- Use reading, practice, discussion, and spaced revision to develop a broader understanding beyond the concepts covered by your preliminary questions.
Conclusion
All being said and done, do not think that pretesting is about celebrating mistakes or getting answers wrong on purpose (how absurd!). Your initial attempt is a way to make subsequent learning more focused and meaningful.
Think back to the questions at the beginning of this article. Their purpose was never to measure how much you already knew, right? Even if the technique is not universally applicable, it does change the way learners approach the unfamiliar.
So, what are you waiting for? Certainly not to study a lesson before you test yourself! Start developing your personal pretesting routine, play around with it a bit, and don’t be afraid to get it wrong because this might just help you get it right.
