About this course
This course prepares students for the Cambridge O Level Chemistry examination (Syllabus 5070). Students will explore the fundamental principles of chemistry including atomic structure, bonding, chemical reactions, the periodic table, organic chemistry, and environmental chemistry. The course develops scientific thinking, laboratory skills, and the ability to apply chemical concepts to real-world situations. Ideal for students in Grades 9–10 seeking a strong foundation for A Level sciences, medicine, pharmacy, or chemical engineering.

Exam pattern
Every paper is marked by Cambridge (externally assessed). Students who study online usually sit Paper 4, as it needs no lab — your exam centre confirms which practical paper it offers.
Grades
A*, A, B, C, D, E. 'Ungraded' means below E and is not shown on the certificate. Your certificate says GCE O LEVEL.
What it took in June 2026
| Grade | Marks out of 200 | Roughly |
|---|---|---|
| A* | 160–164 | about 80–82% |
| A | 129–133 | about 65–67% |
| B | 98–102 | about 49–51% |
| C | 65–71 | about 33–36% |
| D | 55–58 | about 28–29% |
| E | 45–48 | about 23–24% |
Minimum weighted marks out of 200 in June 2026 (the range covers the different paper variants). Boundaries move a little every series — aim well above them.
Cambridge says students with A* to C are well prepared to go on to AS & A Level Chemistry. Medicine, pharmacy and engineering pathways usually expect an A or A*.
