Physics can be a challenging subject for many students in secondary school education, as it combines abstract concepts, complex mathematical equations, and real-world problem-solving. Despite its difficulty, physics is an important subject—often a prerequisite for university courses, especially in Engineering and other science-related fields.

To succeed in physics exams, whether at International GCSE or A-Level, students need an analytical mindset, consistent effort, and plenty of practice. To help make your exam preparation more effective, we spoke with one of our experienced physics teachers, who shared valuable tips based on years of teaching and marking exam papers. Here’s what he advises for students preparing to take their upcoming physics exams.

Tip 1: Read the units for measurements correctly

An important tip when solvinig Physics questions is to read the units carefully and convert them to the correct base units whenever necessary. For example, whenever a physical quantity is substituted into a formula, it should be converted into its base (eg, 5 km = 5000 m). Doing this not only shows your understand the question thoroughly, but also helps you avoid simple mistakes that can cost you marks on your exam.

Remember that a number without a unit will not make sense in Physics, so make sure not to leave out the correct unit in the final portion of the calculation. By writing the unit clearly, you show that you truly understand the concept behind the calculation. This small habit can be the key to moving from a ‘B’ grade to an ‘A’ grade.

Tip 2: Utilise the entire graph sheet

When drawing graphs in Physics, it is important to use the full sheet to present your data clearly. Graphs often involve plotting values against quantities that increase linearly, such as time, temperature, or gravitational strength. Marks are awarded not only for accurate calculations but also for how well the graph illustrates the relationship between variables.

Choose an appropriate scale for both the X and Y axes so that your points are evenly spread across the sheet. This makes it easier to plot accurately and draw a reliable best-fit line or curve. 

Drawing graphs that are too small can cost you marks, even when their calculations are correct. Using the entire sheet helps you avoid this and present your work more effectively.

Tip 3: Memorise definitions

There are many questions in Physics that require you to understand and write down the proper definitions using relevant scientific terms. In certain cases where there may be alternative ways of expressing a concept, it is imperative to use the correct terminology when writing down your definition.

Using alternative words or rewriting a definition without the specific terms of the set definition will result in lost marks. Teachers are not looking for creative writing, but rather a student’s ability to remember specific quotes or definitions.

A useful way to prepare for such questions is to focus on the key words and phrases within each definition and practise them regularly, both in and out of class. This strengthens recall and increases your chances of getting full marks in definition-based questions on Physics exams.

Tip 4: Write down the formulas

When answering Physics questions, write down the formulas you need. Since the subject relies heavily on formulas, teachers expect you to use them to explain and solve problems. It also shows how well you understand the concept.

Writing the correct formulas will not only help you to get more marks, but it will also save time when explaining something. Even if your final calculation is incorrect, writing the right formula will still be rewarded with some marks for presenting the correct method.

Tip 5: Show the workings of calculations

Always show all the necessary steps in your calculations, including the formulas used, the substitutions made, and the conclusion. Examiners award marks for method as well as the final answer, so skipping steps can cause you to lose marks, even if your final answer is correct.

Double-check your calculations in an exam, so that any mistakes that you may have made when tackling a scenario can be identified and then corrected. Also, avoid spending too much time on one question, so you will have adequate time to check through answers and ensure that careless mistakes are spotted and corrected.

Tip 6: Focus on both concepts and numericals

When studying Physics, make sure you spend time on both theory and numerical questions. Understanding the concepts helps you see how formulas work and why certain methods are applied, which makes tackling numerical questions easier. At the same time, practising numericals strengthens problem-solving skills and prepares you for applying concepts under exam conditions.

Maintaining a balance between the two ensures that you are not only memorising facts but also developing the ability to use them effectively in different types of questions.

Tip 7: Start with the easy topics first

Begin with topics you are more confident in, especially those that carry higher weightage in your Physics exam. Starting with the most difficult questions may feel overwhelming and take up too much time. By beginning with simpler, more manageable topics, you build confidence and create momentum before moving on to the harder ones.

Don’t let the complex topics stop you from learning & mastering Physics

While the best technique to study and prepare for Physics exams varies from student to student, the strategies above can serve as practical tips to help you approach questions with confidence. Avoid last-minute cramming whenever possible, and give yourself enough time to review, practise, and strengthen your understanding.

By using the tips and tricks shared above, you can study smarter, not just harder. Focus on building a solid foundation, tackling different question types, and applying what you’ve learned in real-world contexts to make Physics concepts easier to tackle and eventually understand.
