Best Study Techniques Backed by Science for Students

Not all study techniques are equally effective. Some methods feel productive but produce weak results, while others feel more difficult but lead to stronger learning.

For example, many students re-read notes, highlight slides, or watch lecture recordings repeatedly. These methods can help you become familiar with content, but they often do not train your brain to recall and apply information independently.

Science-backed study techniques focus on how memory actually works. Instead of simply exposing yourself to information again and again, they help you retrieve, space, test, and apply knowledge.

In this article, we will look at the best study techniques backed by science and how students can use them for exam revision.

1. Active Recall

Active recall is the process of retrieving information from memory without looking at the answer. It is one of the most effective study methods because it forces your brain to practise remembering.

For example, instead of reading:

“Inflation is the general increase in prices over time.”

Ask yourself:

“What is inflation?”
“What causes inflation?”
“How does inflation affect consumers?”
“What is the difference between demand-pull and cost-push inflation?”

This turns studying into a question-and-answer process.

Active recall is closely related to retrieval practice. Research by Roediger and Karpicke showed that taking memory tests improves long-term retention. Students who retrieved information performed better after a delay compared to students who only re-studied.

How to apply it:

  • Cover your notes and write what you remember
  • Use flashcards
  • Attempt practice questions
  • Explain concepts without looking
  • Turn lecture slides into questions

Quizzy can support active recall by converting Kahoot or Wooclap PDF question sets into clean question-only quizzes. This helps students test themselves without seeing answers too early.

2. Practice Testing

Practice testing is one of the most strongly supported learning techniques. It does not only measure what you know — it also improves learning.

Dunlosky et al. reviewed several common learning techniques and identified practice testing as a high-utility method. This means it is effective across many learning conditions and can be used by many types of students.

Practice testing works because it creates effort. When you try to answer a question, your brain searches for the information, rebuilds the memory, and strengthens access to it.

Examples of practice testing include:

  • Past-year papers
  • Short-answer questions
  • Multiple-choice quizzes
  • Flashcards
  • Self-made questions
  • Kahoot or Wooclap question sets

A common mistake is reading the answer too quickly. To get the full benefit, attempt the question first. Even if you are unsure, make a genuine attempt before checking.

3. Spaced Repetition

Spaced repetition is the practice of reviewing information across multiple sessions separated by time.

Instead of studying one topic for three hours in one day, you might review it for shorter sessions across several days.

For example:

  • Day 1: Learn the concept
  • Day 2: Test yourself
  • Day 4: Review mistakes
  • Day 7: Attempt questions again
  • Day 14: Do a mixed-topic quiz

This method is based on the spacing effect. Cepeda et al. reviewed hundreds of studies on distributed practice and found that spaced learning improves retention compared to massed learning.

Spaced repetition works because forgetting is natural. When you review information after some delay, your brain has to work harder to retrieve it. This effort strengthens memory.

How to apply it:

  • Review difficult topics more frequently
  • Increase intervals for topics you know well
  • Use a calendar or study planner
  • Re-test yourself instead of just re-reading
  • Combine spaced repetition with Quizzy question sets

4. Interleaving

Interleaving means mixing different types of questions or topics during practice instead of studying one topic at a time for too long.

For example, instead of doing:

  • 20 accounting questions on depreciation only

You might mix:

  • Depreciation
  • Inventory valuation
  • Financial ratios
  • Cash flow statements

This is useful because exams often mix topics. Interleaving trains your brain to identify which method or concept is needed for each question.

Interleaving can feel harder than blocked practice, but that difficulty is part of the learning benefit. It forces you to compare concepts and select the right approach.

How to apply it:

  • Mix old and new questions
  • Combine easy and difficult topics
  • Create topic-randomised quizzes
  • Use Quizzy question sets across multiple lecture PDFs

5. Elaboration

Elaboration means explaining ideas in more detail and connecting them to what you already know.

For example, instead of memorising:

“Cybersecurity risk is the possibility of loss caused by digital threats.”

You can ask:

“Why does cybersecurity risk matter to businesses?”
“How does this relate to data breaches?”
“What is an example from real life?”

Elaboration helps you understand concepts instead of memorising isolated sentences.

How to apply it:

  • Ask “why” and “how” questions
  • Create examples
  • Compare related concepts
  • Explain ideas in your own words
  • Link theories to real-world scenarios

This is especially useful for essay-based subjects, business modules, humanities, and technical concepts that require explanation.

6. Dual Coding

Dual coding means combining words and visuals to improve understanding. For example, you might pair written notes with diagrams, flowcharts, timelines, or tables.

This works well for subjects that involve processes, relationships, or systems.

Examples:

  • Use a flowchart for a business process
  • Use a timeline for history
  • Use a diagram for biological systems
  • Use a table to compare theories
  • Use a mind map for broad topics

However, visuals should support understanding, not replace active recall. After creating a diagram, test yourself by drawing it again from memory.

7. Teaching the Concept to Someone Else

Teaching is powerful because it exposes gaps in your understanding. If you cannot explain a concept simply, you probably do not understand it fully yet.

You do not always need another person. You can:

  • Explain the topic out loud
  • Record yourself
  • Write a simple explanation
  • Teach an imaginary student
  • Create a mini-summary without notes

This works especially well after doing practice questions. If you get a question wrong, try explaining the correct answer in your own words.

How to Combine These Techniques Into One Study System

The best results usually come from combining multiple science-backed study techniques.

Here is a simple workflow:

  1. Learn the topic from lecture notes
  2. Convert lecture quiz PDFs into questions using Quizzy
  3. Attempt the questions using active recall
  4. Review mistakes
  5. Re-attempt difficult questions after a few days
  6. Mix questions from different topics
  7. Explain difficult answers in your own words

This system combines:

  • Active recall
  • Practice testing
  • Spaced repetition
  • Interleaving
  • Elaboration

It is much stronger than simply reading notes repeatedly.

Why This Matters for Students

Good study techniques save time. They help students focus on what actually improves memory and exam performance.

This is especially important when students receive many learning materials from lecturers, including slides, PDFs, Kahoot quizzes, Wooclap activities, tutorial questions, and answer sheets. Without a system, it is easy to feel overwhelmed.

Quizzy helps by turning existing question-and-answer PDFs into question-only revision materials. This makes it easier to test yourself properly and use evidence-based learning methods.

Final Thoughts

The best study techniques backed by science are not always the easiest. Active recall, practice testing, and spaced repetition require effort, but that effort is exactly why they work.

To study better, focus on techniques that make you retrieve, apply, and review information over time.

Use re-reading only as a starting point. Then move quickly into self-testing, spaced review, and practice questions.

That is how students can study smarter, remember more, and prepare more effectively for exams.
