Frequently asked questions
- When are Cambridge 9618 results 2026?
- AS & A Level grades for the June 2026 series release 11 August 2026 (05:00 GMT). Component grade threshold tables typically follow around 13 August. IGCSE/O Level grades release 18 August. Subject checklist: /results-2026/caie/9618.
- How do I check if my 9618 grade will hold?
- Paste your Computer Science (9618) raw mark and recent or official thresholds into Will my grade hold? — you will see the predicted grade and marks to the next boundary. Always confirm against your official statement.
- Can MarkScheme mark Computer Science (9618) handwriting?
- Yes — upload photos of your A-Level Computer Science answers. We score against Cambridge mark schemes for syllabus 9618, including method marks and essay bands where applicable.
- Do I need the official 9618 mark scheme PDF?
- MarkScheme uses mark-scheme logic for 9618. For your own study, always download the official paper and mark scheme for the same exam series from Cambridge or your school.
- Is this a replacement for my teacher?
- No — it is a faster second pass when you revise alone. Use strict self-marking first, then MarkScheme to catch what you missed.
