Once you’ve come to the GCE O Level Chemistry you have already grasped the basics of chemistry you’ve studied and will be more focused on studying and getting a better understanding of chemistry more in-depth in order to get the best grade for your exam.

Therefore, the best way for students to learn and get the preparation needed for their upcoming chemistry exam is by running through the curriculum.

As students, you will be learning about chemical changes, chemistry concepts, atoms – the structure as well as the periodic table.

In Chemistry, it teaches students that not only will the learning of theory be adequate but they will also be tested on their practical skills in the laboratory and would be prepared to conduct and plan experiments – ultimately writing their findings and analyzing its results.

The process of studying for your exams could indeed be overwhelming at the start – however, once you get started you would be gaining a better understanding of the chemistry curriculum and the knowledge needed to achieve high grades for your exams.

This article will take you through some of the most important points for sitting the O level chemistry exam (regardless of which curriculum you belong to as chemistry is universal!) 

This article will cover the following points:

1 – common mistakes made by students in the O Level Chemistry 

2 – Study tips to ace your O Level Chemistry exam

3 – Where to find additional resources

1 – common mistakes made by students in the O Level Chemistry

When revising for Chemistry there are many mistakes which students often make which are crucial to be corrected before the exam in order for the student to improve.

Here is one common mistake made by students in their O Level Chemistry: 

Students often write a summarised description when a question specifies an explanation in which chemistry examiners expect. Therefore the description alone will not give them marks. Hence, it is crucial to get into the habit/practice of demonstrating those answers with the use of correct scientific vocabulary as it teaches students how to score better.

2 – Study Tips for O Level Chemistry 

Science subjects such as Chemistry are extremely useful as it provides definitions on terms which often enables students score’s to be better.

There will also be a clear-cut set of examples to be remembered in detail along with different chemistry concepts where once it’s embedded into your mind, you would always be able to answer any question well.

Familiarise yourself with definitions and calculations  

With chemistry, it is different from when studying Biology. You often need to familiarise yourself with not only definitions but also calculations along with their processes.

Practising more past year papers 

Past papers for chemistry exams are a vital tool for students when revising. By practising with past papers, you would be able to get a better grasp of how the exam paper will be structured. While you get a better understanding of the structure – you could also look over the Mark Schemes which would highlight the errors made and correct them in order for students to improve.

There are often key terms in Chemistry concepts that need to be covered in order to get marks – therefore, it would mean that the chemistry exam is not marked based on just the student’s knowledge of the subject but you are expected to answer all questions based on how the chemistry examiners expect you to.

Therefore, with thousands of students across the country sitting for this chemistry exam in the coming months, mark schemes are seemingly changing, often increasing the more challenging questions for junior college level students.

We have noted some past papers along with their mark scheme to help students answer effectively.
