In the wake of Covid, GCSE Physics exams have shifted towards providing students with equation sheets, sparking debate about whether memorising equations is still necessary. This change aims to reflect real-world practices, but does it diminish the importance of learning formulas by heart? Here’s my (slightly biased) take on the argument.

Why Memorising Equations Still Matters

Even with an equation sheet in front of you, there’s a lot of value in knowing key formulas by heart. For starters, it saves time. Instead of flipping through a list mid-exam, you can dive straight into the problem. That time-saving can make a big difference when you’re up against the clock.

Memorising also helps you understand the equations better. When you’ve got a formula like F = m x a locked in your memory, it’s easier to see how the variables interact. You’re not just plugging numbers into a formula—you’re thinking about the science behind it.

Plus, memorisation builds confidence. Walking into an exam knowing you can recall the basics without relying on a sheet feels empowering. And let’s not forget the long-term benefits. If you’re considering A-levels, university, or a career in STEM, you’ll need to know certain equations by heart eventually. It’s good practice for the future.

The Case for Equation Sheets

On the flip side, equation sheets make a lot of sense. They reflect how things work in the real world. Engineers, scientists, and mathematicians don’t memorise every single formula—they use tools, resources, and references to solve problems. Equation sheets in exams mirror this, teaching you how to apply knowledge rather than test your ability to memorise.

They also shift the focus. Instead of worrying about recalling formulas, you can put your energy into solving problems and showing your understanding. This is a big win for students who might struggle with memory but excel at critical thinking.

Lastly, let’s be honest—equation sheets can take a lot of the stress out of exams. They help level the playing field, ensuring that what’s being tested is your comprehension and application skills, not just your ability to memorise under pressure.

How GCSEs Find the Middle Ground

The introduction of equation sheets in GCSE Physics is all about balance. While you’re not required to memorise every formula, knowing the most important ones can still give you a real advantage. For example, being familiar with frequently used equations saves time and reduces the chance of errors when you’re under exam conditions.

At the same time, using an equation sheet effectively is a skill in itself. Knowing how to quickly find what you need and apply it to the question is just as important as understanding the equations in the first place.

The Best Approach: A Bit of Both

The debate over memorising equations versus relying on equation sheets doesn’t need to be an either/or situation. A balanced approach is the way forward. Start by memorising a few essential equations, especially the ones that come up repeatedly. This builds your confidence and helps you understand the core concepts.

At the same time, practise using the equation sheet so you’re comfortable with it in an exam setting. Learn how to find the formulas you need quickly and apply them to different problems. This way, you’re prepared for any scenario—whether you’re given a sheet or not.

What’s Your Take?

So, where do you stand? Should students focus on memorising equations, or is it better to rely on equation sheets? Maybe there’s a balance to be struck? Let us know your thoughts—we’d love to hear from you!
