To best prepare for the Chemistry O-level paper, we recommend students start by getting their foundations right before moving on to more challenging topics.
Begin with these topics
1.1 Experimental Design (Experimental Chemistry)
1.2 Methods of Purification and Analysis (Experimental Chemistry) 2.1 Kinetic Particle of Theory (The Particulate Nature of Matter) 2.2 Atomic Structure (The Particulate Nature of Matter) 3.1 - 3.3 Ionic Bonding, Covalent Bonding, and Metallic Bonding (Chemical Bonding and Structure)
After having mastered the basics, move on to Chemical Calculations to get your chemical calculations right. After you’ve done that, move on to Acid-Base Chemistry and Qualitative Analysis, where you’ll be studying the 3 highly connected topics: Acid & Bases, Salts, and Qualitative Analysis.
