O Level Chemistry (5070) – Complete Guide for May/June 2026 CAIE Exams (Notes, Syllabus, Tips, Past Papers)
Are you ready to turn your chemistry confusion into a distinction? You have landed on the single most comprehensive resource for CAIE O Level Chemistry (5070) on the web.
This is not just another blog post. This is your 2025 Exam Roadmap. Whether you are a student targeting an A*, a parent looking for the best learning resources, or a teacher seeking editable lesson plans, this guide delivers the exact tools you need to succeed.
Why Most Students Struggle (And How You Won’t)
Chemistry is the bridge between Physics and Biology, but it is notorious for its “abstract” concepts. Many students lose marks not because they don’t study, but because they study wrong.
Common Pitfalls include:
❌ Rote Learning: Memorizing definitions without understanding the keywords.
❌ Math Phobia: Failing to visualize stoichiometry calculations.
❌ Practical Neglect: Ignoring Paper 4 requirements until the last week.
Our Approach: We combine official Cambridge syllabus insights, examiner-verified strategies, and premium resources to simplify the complex.
1. The 2025 Syllabus: A Strategic Breakdown
The Cambridge O Level Chemistry (5070) syllabus for 2025 has evolved. It now places a heavier emphasis on the application of knowledge rather than just recall.
Assessment Weighting (Know Your Numbers)
To maximize your score, you must understand where the marks come from.
| Paper | Component | Duration | Marks | Weighting | Vital Strategy |
| Paper 1 | Multiple Choice | 1 Hour | 40 | 27.6% | Speed & Elimination. Practice 1000+ MCQs. |
| Paper 2 | Theory | 1h 45m | 80 | 51.7% | Specific Keywords. Explain “Why” and “How”. |
| Paper 4 | Alt. to Practical | 1h | 40 | 20.7% | Observations, Colors, and Data Analysis. |
What to Study First?
If you are short on time, prioritize these high-yield topics:
Stoichiometry (Moles): The backbone of calculations.
Organic Chemistry: High memorization, high reward.
Electrolysis: Conceptually difficult but repetitive questions.
Acid, Bases & Salts: Essential for Paper 4.

2. Mastering the “Grade-Killer” Topics
We have analyzed thousands of past papers. These are the topics that separate the A* students from the B grades.
A. Stoichiometry: The Math of Chemistry
“Moles” is the most feared word in O Level Chemistry. It doesn’t have to be. The secret is using visual tools like the Formula Triangle.
Pro Tip: Always convert units first! ($cm^3 \rightarrow dm^3$).

B. Organic Chemistry: The Big Pattern
Organic Chemistry makes up nearly 20-25% of Paper 2. It looks like a lot to memorize, but it follows a strict pattern of Homologous Series.
Why This Matters: If you understand how Alkanes become Alkenes (Cracking) and how Alkenes become Alcohols (Hydration), you don’t need to memorize every single reaction individually. Connect the dots!

C. The Periodic Table & Trends
Understanding why elements react (Periodicity) allows you to predict answers even if you haven’t memorized the specific reaction.
