S3 Content Mastery Course

Become Great At Tackling Questions on
“Atomic Structure”!

What Your Child Will Be Learning

During this content-packed masterclass, we’ll work closely with your child to improve his/her answering techniques to tackle questions on the topic of Atomic Structure.

🧱 Understand Key Science Concepts, Master Various Question Trends & Question Types

We’ll help to break down complex Atomic Structure concepts using coloured illustrations, comparison charts and worked examples. Next, we’ll help your child relate these concepts to different scenarios so that he/she is better able to understand how these concepts work.

Our S3 Atomic Structure Masterclass is all about understanding various examination question trends and question types & how to apply our tested and proven answering techniques to tackle these questions.

Knowing how questions may possibly be tested during examinations will help your child understand what to study and how to study. This also means that your child will be better equipped to tackle similar questions during his/her examinations and hence will be able to process these questions a lot faster than his/her peers.

If your child diligently reviews and applies what we’ve taught, he/she will definitely make progress in their abilities to tackle Atomic Structure questions.


🚀 Valuable Examination-centric Resources To Accelerate Understanding

Your child will NOT leave this workshop empty-handed.

Not only will our Chemistry Specialists take your child through the step-by-step process of tackling Atomic Structure questions, we’ll also provide your child with beautifully-illustrated notes, worksheets and worked examples that are designed to help students learn this topic easier, better and faster.

These valuable resources will help to shorten the learning curve tremendously. You and your child can expect to save lots of valuable time and frustration trying to figure out what examination setters are looking out for.

Here’s a sample of what your child will receive…


đź’Ł Avoid ‘Concept Traps’ That Cause Most Students To Lose Marks Unnecessarily

It is important to have an understanding of the common conceptual pitfalls so that your child can learn to avoid them. We also included little ‘warning notes’ to remind students of potential misconceptions in their syllabus.

Do not underestimate these tips as they will help your child improve the odds of scoring an A1 for his/her Science examination!
