The Real Difference Between A and A* Students (It's Not More Revision)

Every teacher has taught this student.

They work hard, they know the content, they attend revision sessions, they complete the past papers, and yet, when results day arrives, they miss out on the top grade.

Maybe they achieve a B when they were capable of an A.

Maybe they achieve an A when an A* felt within reach.

The obvious response is often to focus on knowledge gaps: more revision, more content, more exam practice...but after teaching A Level Biology since 2009, I've become increasingly convinced that knowledge is only part of the picture. The students who consistently move from good grades to exceptional grades often aren't the students who know the most. They're the students who think differently about learning, and that's why mindset matters.

Not in a motivational-poster kind of way, but in a practical, classroom-based, evidence-informed way that helps students persevere when learning becomes difficult.

Why Knowledge Alone Doesn't Create A* Students

When I recently delivered a CPD session called The A Blueprint*, I opened with a statement that surprised some teachers:

An A is not simply the result of knowing more content.*

Content knowledge is essential. Exam practice is essential. Revision is essential. But when I look at the students who make the leap from A to A*, three factors consistently stand out:

1. Strong Exam Skills

Top-performing students understand how to interpret questions, identify command words, and apply knowledge in unfamiliar contexts.

2. Effective Revision Habits

They use retrieval practice, spacing, and active revision strategies consistently rather than relying on passive methods.

3. Productive Mindset

This is the factor that is often overlooked. A* students are more likely to persist when they encounter difficulty. They see mistakes as information rather than evidence of failure. And they view challenge as part of learning rather than proof that they aren't capable.

What Fixed Mindset Looks Like in the Classroom

Many teachers are familiar with the term "fixed mindset", but it's often easier to recognise in theory than in practice.

In reality, it sounds like this:

• "I'm just not naturally good at maths."

• "I can't write essays."

• "I've always been bad at exams."

• "It's too late to change how I revise."

• "I failed that test, so I'm never going to understand this."

These comments might seem harmless, but they reveal beliefs that actively prevent improvement. Students begin to view ability as fixed rather than something that can be developed, and this can become particularly problematic at A Level.

Why A Level Can Trigger Confidence Crises

Many students arrive in Year 12 after experiencing considerable success at GCSE.

Then they encounter the complexity of A Level Biology.

The content is harder, the application is more demanding and the exam questions are less predictable.

For the first time, some students struggle. The challenge isn't necessarily the difficulty itself, it's the story students tell themselves about that difficulty.

Some students think:

"This is hard. I need to adapt my approach."

Others think:

"This is hard. Maybe I'm not clever enough."

That difference in interpretation can have a significant impact on long-term performance.

Why Teachers Need to Teach Mindset Explicitly

One of the biggest mistakes schools make is assuming mindset develops naturally. We explicitly teach revision techniques and exam skills, but mindset is often left to chance. Instead, it should be embedded into teaching from the beginning of Year 12.

Students need to understand:

• How learning actually works

• Why struggle is normal

• What resilience looks like in practice

• How mistakes contribute to improvement

When these conversations happen early, students are far more likely to persevere when challenges arise later.

The Learning Pit: A Powerful Tool for Productive Struggle

One strategy I use regularly is the Learning Pit. The Learning Pit helps students understand that learning is rarely a straight line.

The process often looks like this:

1. Initial confidence

2. Confusion

3. Frustration

4. Persistence

5. Understanding

Students often assume that feeling confused means something has gone wrong; The Learning Pit reframes confusion as an expected stage of learning.

When students say:

"I don't get this."

You can respond:

"Good. You're in the pit. That's exactly where learning happens."

Over time, students begin to see challenge as a sign of progress rather than failure.

The Iceberg Illusion: What Students Don't See

Students often compare themselves to successful peers without understanding the work that happens behind the scenes.

They see:

• The A*

• The confidence

• The success

What they don't see is:

• The mistakes

• The failed tests

• The uncertainty

• The hours of practice

• The setbacks

This is known as the Iceberg Illusion, the visible success sits above the surface. Everything that created that success remains hidden underneath.

Teaching students this concept helps normalise struggle and reduces the belief that successful people find everything easy.

Why Language Matters More Than We Think

Small changes in teacher language can have a significant impact.

Consider the difference between these two statements:

"This is a really hard question. Don't worry if you can't do it."

Versus:

"This should feel uncomfortable. That's how you know you're learning."

The first statement lowers expectations, while the second reframes challenge as a positive experience. When students repeatedly hear difficulty described as part of growth, they become more willing to engage with challenging work.

Using Challenge Questions to Build Resilience

One of the simplest mindset interventions is the regular use of challenge questions.

These questions should:

• Stretch students beyond their comfort zone

• Require application rather than recall

• Create opportunities for productive struggle

The key is how they are introduced.

Before students begin, I often say:

"You will get confused at some point during this task."

"I expect you to need help."

"That isn't a problem. That's the process."

This removes the stigma associated with not knowing the answer immediately and helps students learn that confusion is expected, not embarrassing.

Turning Failure Into Action With MARCKS Analysis

One of the biggest barriers to improvement is viewing test results as a verdict.

Many students see a disappointing score and conclude:

"I'm bad at this."

Instead, I encourage students to analyse where marks were lost using a MARCKS analysis.

Students identify whether mistakes were caused by:

• Maths

• Application

• Reading the question

• Clarity of answer

• Knowledge

• Statements per question

This transforms failure into useful information.

Instead of asking:

"Why am I bad at Biology?"

Students begin asking:

"What specifically should I improve next?"

That shift is incredibly powerful.

How to Start Embedding Mindset Tomorrow

If this all sounds overwhelming, start small.

The next time you hand back a test:

Before students see their marks, spend five minutes discussing the Iceberg Illusion.

Talk about what success really looks like.

Remind students that grades are data, not identity.

Then ask them one simple question:

"What is the next thing you need to improve?"

That single conversation can begin changing how students view challenge, mistakes and progress.

The Difference Between A and A* Students

The highest-achieving students aren't always the smartest or the most naturally gifted, and they don't always revise the most. What often separates them is their response to difficulty: they understand that struggle is part of learning, see mistakes as feedback, they persist when others give up, and they believe improvement is possible.

If we want more students reaching top grades, we need to stop treating mindset as an optional extra.

Because sometimes the biggest barrier between an A and an A* isn't knowledge at all.

It's what students believe about themselves when learning gets hard.

If you want to hear how these ideas play out in real classroom practice, you can listen to the full episode of Miss Estruch Teach & Tell below.

In this conversation, we go far beyond theory and explore exactly what separates A and A* students in the classroom, including real strategies I use to build resilience, confidence, and independent thinking in A Level Biology.

We discuss:

• Why some students stay stuck at A or B grades despite knowing the content
• What fixed mindset actually looks like in real lessons
• How to explicitly teach productive struggle without lowering expectations
• The Learning Pit and Iceberg Illusion in classroom practice
• Practical ways to turn mistakes into actionable improvement using MARCKS analysis
• How to shift student language around difficulty and challenge

This episode is especially useful if you teach A Level or GCSE science and want practical, classroom-ready strategies rather than abstract theory.

FAQ's About Student Mindset

What is the difference between an A and A student?*
While content knowledge matters, A* students often demonstrate stronger exam skills, more effective revision habits, and a mindset that helps them persevere through difficult challenges.

Can mindset really improve student grades?
Yes. Students with a growth mindset are more likely to persist when work becomes difficult, learn from mistakes, and use feedback effectively, all of which can contribute to improved academic performance.

What is productive struggle in education?
Productive struggle refers to the process of grappling with challenging concepts before reaching understanding. It helps students develop resilience, deeper learning, and problem-solving skills.

What is the Learning Pit?
The Learning Pit is a model that helps students understand that confusion and difficulty are normal parts of learning. It encourages students to persist through challenges rather than avoid them.

What is the Iceberg Illusion?
The Iceberg Illusion highlights that we often see other people's success but not the failures, mistakes and hard work that happened behind the scenes. It helps students understand that success is built through effort and persistence.

How can teachers help students develop a growth mindset?
Teachers can explicitly teach mindset strategies, normalise mistakes, use challenge questions, model resilience, and help students view assessment results as opportunities for improvement rather than measures of ability.
