Highlighting notes is one of the most common study habits among students. It feels productive, organised, and even satisfying to see pages filled with colour. However, it rarely leads to strong exam performance.
If you have ever highlighted an entire page only to realise you do not remember much later, you are not alone. The problem is not effort. It is the method being used.
If you are looking for effective study techniques for exams, it is important to understand which methods actually work and which ones only feel productive.
Let’s break down why highlighting does not work as well as you think, and what you should do instead.
The Illusion of Learning
Highlighting creates a false sense of understanding.
When you reread highlighted notes, the information feels familiar. Familiarity is not the same as being able to recall or apply information under exam conditions. This is why highlighting often feels effective without actually improving memory.
It’s Too Passive
Highlighting is a passive activity. You are identifying information, not actively thinking about it.
Without challenge, your brain does not build strong memory connections. In contrast, techniques like explaining ideas, answering questions, and applying knowledge are far more effective study techniques for exams because they require real thinking. Effective study techniques require students to actively engage with the material, not just identify it.
It Does Not Train Recall
Exams test recall, not recognition. When notes are removed, recognition is no longer enough to support performance.
Highlighting trains you to recognise information, not retrieve it. When your notes are gone, that recognition disappears, which is why many students struggle in exams despite spending hours revising.
It Encourages Over Highlighting
Many students end up highlighting too much.
When everything is marked, nothing stands out. Your notes become cluttered and less useful, making highlighting even less effective as a study technique for exams.
What Works Better Instead?
To improve both memory and exam performance, you need to shift from passive to active study methods.
Here are some of the most effective study techniques for exams:
1. Active Recall
Close your notes and try to remember key information from memory.
For example:
- Write down everything you know about a topic
- Answer questions without checking your notes
- Explain the concept out loud as if teaching someone else
This strengthens your ability to retrieve information, exactly what you need in exams.
2. Practice Questions
Applying knowledge is one of the fastest ways to learn.
Use past paper questions or textbook exercises to:
- Test your understanding
- Identify weak areas
- Become familiar with exam style questions and expectations
3. Summarising in Your Own Words
Instead of highlighting, rewrite key ideas simply.
This forces you to process the information and check whether you truly understand it, not just recognise it.
4. Spaced Repetition
Revisit topics over time instead of cramming.
Reviewing information at intervals helps move it into long term memory, making it easier to recall under exam conditions.
Improving Your Study Techniques for Exams at ITG
Highlighting can support organisation, but it should not be a your primary study method. It helps organise information, not remember it.
To succeed in exams, students need to focus on active approaches like recalling, applying, and explaining ideas. These are the study techniques that build real understanding and long term memory, both of which are essential for exam success.
The most effective study techniques are those that mirror what students are required to do in exams. At International Tutor Group, we support students in moving beyond passive habits and developing effective study techniques for exams that truly work. Through personalised guidance across IB, IGCSE, and A Level, our tutors help students build confidence, improve retention, and apply their knowledge effectively in exams.
