‘O’ Level is around the corner.


As you prepare for your O-Level exams, you’ve probably realized how frustrating it is to lose marks due to simple, careless mistakes. Think back to all the times you’ve added up the marks you lost just because of carelessness—those marks could have made a big difference! These can sometimes cost you a grade or even two.


You can be careless-free!


Be awarded the marks you deserve.


There are strategies you can apply to minimize those pesky errors. Here are 8 strategies to help you stay sharp and be careless-free during your exams and ace your papers.


1. Re-Do the Questions


When you finish solving a question, don't rush to move on to the next one. Take a moment to re-read the question and redo it.


Solve it from scratch and go through your steps again. Sometimes, during this quick review, you may notice a miscalculation or an overlooked instruction. That extra check could prevent a lost mark.


For example, in a math question, you might realize you forgot to carry over a digit or misread a decimal point.

For science papers, students are prone to misunderstand the questions and give the wrong keywords.


Checking your papers is critical to catching any careless mistakes—especially the ones that slipped past you the first time. This is where practice and time management come into play.


Tip: Use this strategy during timed practice sessions to simulate the actual exam experience.

 

2. Highlight Important Information

For subjects like math, it’s important to write down key information clearly. For science, underline or highlight important terms in the question. By doing this, you’re making the problem easier to follow and ensuring you don’t miss critical details.


It may sound simple, but missing a unit or a key word could make the difference between the correct answer and a wrong one.




For instance, highlighting keywords like "increases," "decreases," or "constant" can help you focus on the critical aspects of the problem.


3. Write Down Every Step of Your Working


In math and science exams, skipping steps in your working might seem like it saves time, but it often leads to missed errors.


Don’t neglect the various factors which might cause you stress like time, environment and the frantic search of knowledge in your brain. If you’ve written down your steps, it’s easier to check your work and see where you might have gone wrong.


Examiners award marks for working, even if your final answer isn’t correct. It's worth those extra few seconds to write it all down.


4. Write Legibly

I understand when one is under pressure, your handwriting can be the cause of your loss. The number ‘3’ may be written as ‘5’, or the number ‘4’ can be read as ‘9’.


Writing legibly is not just so that the examiner can understand what you’re writing and award you the marks you deserve, but also for yourself to understand when you are checking!


You won’t be able to know the final answer as per your practice to see if you got the right answer. So, write down your workings in a clear, concise, and structured format, and write your answers legibly!


5. Practice Makes Perfect—And Careless Mistakes Fewer


While understanding the concepts is key, practicing as much as possible is equally important. The more questions you solve, the more familiar you become with different question types.


This helps build ‘muscle memory’, so that when you're in the exam room, solving becomes second nature. The more you practice, the less likely you are to make careless mistakes.


6. Do Timed Practice

When you practice, make sure to do it under timed conditions to simulate the exam environment. This helps you build not just accuracy, but speed and endurance as well.


Eliminate distractions!


Turn off your phone and focus completely on the task at hand, just as you would in an actual exam. The more timed practice you do, the more confident and prepared you’ll feel.

It’s just like training for a sport—muscle memory and experience make all the difference.


7. Don't Forget Your Units


This might seem minor, but forgetting to write down units is a common careless mistake, especially when you’re nervous or in a rush.


Writing down the units in your working helps you follow your thought process more clearly. For instance, mixing up centimeters and meters or forgetting to convert units can cost you marks.


Take your time to ensure that all your units are correct, and you’ll save yourself from these simple yet costly errors.


8. Slow Is Fast


It’s easy to feel pressured by time in an exam but remember: rushing increases the risk of making mistakes. Instead, slow down and focus on accuracy.

Take just enough time with each question and aim to do it right the first time. This way, you won’t have to spend extra time fixing errors later, allowing you to stay calm and confident throughout the exam.



Imagine the realization of making a careless mistake at the start of your 10-marks question. You’ll need to redo the question, doubling the time taken!


Do it once, do it right.


Remember, careless mistakes are preventable. You can stop losing a grade due to carelessness.


Everyone can be careless-free!


With the right strategies and plenty of practice, you can walk into your National Exams with confidence, knowing that you’ve done everything you can to minimize errors.


Stay focused!


All the best for your examinations!
