Science (Chemistry) Revision Lessons For WJEC Students

About Course

In this lesson, I have summarised everything you need to succeed and achieve excellent results in your WJEC Science (Chemistry) exams. I have also included an introductory lesson to guide you on how to effectively prepare for your exams in general.

Please note that all our lessons are designed to be simple, concise, and easy to understand. They are delivered in a fun and engaging way to help you fully grasp each topic.

Each lesson in this course includes:

Practice questions (mainly from WJEC past exam papers) presented as quizzes
Assignments based on WJEC past questions

I strongly encourage you to attempt all the questions, as consistent practice is key to achieving top results in your exams.

In this course, you will cover the following topics:

Introduction to Chemistry and Atomic Structure.
The Periodic Table and Trends
Chemical Bonding
Acids, Bases and pH
Chemical Reactions and Equations.
Rates of Reaction
The Mole Concept and Stoichiometry
Chemical Analysis
Organic Chemistry and Hydrocarbons
Electrochemistry and The Reactivity Series

I wish you all the best.
