# A General Guide On Excelling In Your Physics Examinations

There are various ways people consider a person to be proficient in physics. Grasping the multiple concepts quickly is not the only predictor of success when it comes to physics. Another significant predictor is hard work. Hence, it is possible to get good marks in physics if you pick up the fundamental skills and practice what you learnt. One way to do so is by going for physics tuition, or if you are in JC, you can opt for JC physics tuition. However, the journey to getting good marks is not limited to merely learning and practising. Here are some tips that might benefit you.

Memorise the basic constants

There are certain recurring constants that are assigned in physics. Constants are representations that are assigned to the same numbers that don’t change regardless of how or where they are used. In order to fare well in physics, it is essential to memorise them because the majority of tests do not provide these constants. Some of the most commonly used constants in physics are listed below:

• Gravity on earth – 9.81 m s-2
• Molar gas constant – 8.32 J mol-1 K-1
• Planck’s constant – 6.63 x 10-34 m2 kg s-1
• Speed of light – 3 x 108 m s-1

Memorise the basic equations

Physics equations represent how the forces in the universe relate. They range from simple equations to complex ones. It may be difficult to memorise all the equations in physics, but getting started with the simple and basic ones significantly improves your exam results. Most of the time, complex problems are easily solved by the basic, fundamental equations. So, setting time aside to memorise and master these simple equations is a good approach for getting higher marks in physics.

Understand how to derive with basic equations

Sometimes the memorisation strategy might not be a good fit for you, especially when you are prone to forget what you’ve learnt over time. If this is you, then the best way to help yourself in acing your physics exams is to learn how to derive with basic equations. You are not memorising them, but knowing how they come about makes you a versatile problem solver because you will be able to apply your understanding of deriving equations to the answer no matter the question.

Take note of the critical information when solving problems

Most questions in physics often contain information that doesn’t help you in solving the problem. When presented with such questions, read through it and identify the key points that will help you figure out what you are trying to solve. This way, you are sure to stick to the scope of the question and answer what you are asked instead of getting distracted by irrelevant information.
