Why Psychology Grades Don't Always Reflect the Effort (According to an Examiner)

By Janette | Psychology Teacher and Examiner | Sherpa Tutor

That might sound surprising, but it's something I see time and time again.

Many students know the Psychology content really well. They can explain Milgram's obedience study, describe the Multi-Store Model or outline the biological approach with confidence. However, when the exam results come back, they're often disappointed.

The good news is that this usually isn't because they don't know enough. More often, it's because they haven't yet mastered the skill of answering exam questions.

If you're a parent reading this, that's actually reassuring. It means your son or daughter may already have the knowledge; they just need to learn how to apply it effectively in an exam.

The Biggest Mistake I See

The most common mistake is answering the topic rather than the question.

For example, if a question asks students to evaluate a theory, many will spend too much time describing it instead. Others write everything they know, hoping they'll pick up extra marks.

Unfortunately, that's not how A Level Psychology is marked.

Examiners are looking for focused answers that respond directly to the question. A shorter, well-structured answer will often score much higher than a longer one that goes off track. When it comes to a 16-mark question, it can be tempting to write as much as possible. In reality an examiner is looking for very specific techniques.

Evaluation Makes the Difference

One of the biggest improvements students can make is developing their evaluation skills.

Rather than simply stating a strength or limitation, students should explain why it matters and link it back to the question. This is often the difference between an average answer and one that reaches the top mark band.

Don't Neglect Research Methods

Research Methods can seem daunting, but confidence comes with practice. Completing a few Research Methods questions each week is far more effective than trying to revise the whole topic just before an exam.

A Message for Parents

You don't need to know Psychology to support your child.

One of the best things you can do is ask them to explain a topic to you. If they can teach it in simple terms, they usually understand it well. Encouraging regular, manageable revision sessions is also much more effective than last-minute cramming.

Final Thoughts

A Level Psychology isn't just about remembering theories and studies; it's about knowing how to use that knowledge in an exam.

I've worked with many students who have improved by one or even two grades simply by refining their exam technique. Once they understood what examiners were looking for, their confidence and results improved dramatically.

If your current grades don't reflect the effort you're putting in, don't be discouraged. With the right support and focused practice, you can absolutely achieve the grades you're aiming for.

If you're looking for personalised A Level Psychology tuition, I'd love to help. My lessons are tailored to each student's individual needs and focus on building confidence, strengthening subject knowledge and developing the exam skills needed to achieve the best possible results.
