Memory myths: What students get wrong about revising

And what to do instead

When it comes to revision, we know that students work hard - but you might not always be revising as effectively as you can.

It’s common to see hours spent re-reading notes, highlighting textbooks, or watching revision videos, only for information to disappear under exam pressure!

This is because students misunderstand how memory actually works.

At EduBridge Tutoring, we regularly help students refine how they revise, not just what they revise.

By addressing common memory myths and replacing them with evidence-based revision techniques that work, students can improve both confidence and results!

So how does memory work?

Memory is not like a storage box where information is simply placed and retrieved. Instead, it is a dynamic process involving:

• Encoding (taking in information)

• Storage (retaining it over time)

• Retrieval (recalling it when needed)

Many ineffective revision habits focus a lot on encoding but neglect retrieval - which is the skill exams actually test.

Myth 1: Re-reading notes alone is effective revision

The Reality

Re-reading creates a false sense of familiarity - students may recognise information on the page but struggle to recall it independently in an exam.

This is known as the illusion of competence - when something feels learned but isn’t securely stored.

What to do instead

Use active recall- active recall involves retrieving information from memory without looking at notes.

Examples include:

• Answering practice questions

• Using flashcards

• Writing everything you remember about a topic from memory

This strengthens neural pathways and improves long-term retention.

Myth 2: Highlighting means I’ve learned it

The reality

Highlighting is passive - it doesn’t require the brain to process or organise information meaningfully.

While it can help identify key points, it does little to improve memory on its own.

What to do instead

Turn notes into questions - after identifying key information, students should:

• Convert headings into questions

• Test themselves regularly

• Explain answers aloud

This transforms passive review into active learning.

Myth 3: Cramming before exams works best

The reality

Cramming may help with very short-term recall but leads to rapid forgetting. It also increases stress and reduces sleep quality, both of which negatively impact performance.

What to do instead: Use spaced practice

Spaced practice involves revisiting topics over time rather than all at once.

For example:

• Review a topic after one day

• Then again after a few days

• Then again after a week

This strengthens memory consolidation and improves recall under pressure.

Myth 4: “I just have a bad memory”

The reality

Most students do not have a “bad memory” - they have not yet been taught effective strategies.

Memory is highly adaptable. With the right techniques, all students can improve recall and understanding.

What to do instead: Build better study habits

Focus on:

• Consistent revision routines

• Active recall techniques

• Regular review

• Clear organisation of content

Small changes in approach often lead to significant improvements!

Myth 6: “More time studying = better results”

The reality

As with most things in life, quality matters more than quantity. Long, unfocused study sessions often lead to fatigue and reduced retention.

What to do instead: Study smarter, not longer

Effective revision sessions include:

• Clear goals

• Short, focused study blocks

• Regular breaks

• Active engagement with material

Students who revise efficiently often outperform those who simply spend more hours studying.

How can parents support better revision?

Parents play an important role in shaping study habits. You can help by:

• Encouraging active revision techniques

• Asking your child to explain what they’ve learned to you or other family members

• Supporting a structured revision schedule

• Focusing on effort and strategy, not just results

When students feel supported and understand how to revise, their confidence grows significantly.

Many common revision habits feel productive but have little impact on long-term learning. By understanding how memory works and using evidence-based strategies like active recall and spaced practice, students can transform the way they revise.

When students develop effective study habits, they not only improve exam performance but also gain skills that will support them throughout their education.
