What you get
- Your marks, your likely grade and your weakest topic straight away, no account needed.
- With a free account: the skills to fix first, a two-week plan and every answer worked through.
- Your result and plan stay in your account, ready when you come back.
How the range is worked out
- Each question has a difficulty level. Difficulty levels are set by our question writers.
- We take off the answers a guesser would get right by luck (one in four on four options). Too few left and we say so rather than guess a grade.
- We find the ability that best explains how many you got right, allowing for how hard those questions were.
- We place that ability among the 13,974 students who sat OCR A-level Computer Science in 2026, and read the grade from the board's published shares: 5.7% got A* and 23.2% A or above.
- Fifteen questions cannot pin down one grade; a full paper narrows it.
- It assumes you sat the exam now. In Year 12, the Year 13 topics will pull it down until you have learnt them.
Questions
How accurate is the grade?
It is a range, because fifteen questions cannot pin down one grade. A full timed paper marked against the grade boundaries is the closer check.
Is it like the real exam?
Partly. OCR papers are written answers, trace tables and code. These questions check the same skills in a quicker form, so treat the grade as a guide.
Is it only for OCR?
The questions follow OCR H446, but the same topics are on AQA A-level Computer Science.
Do I need an account?
No. Your marks, likely grade and weakest topic show straight away. A free account adds the lesson for each weak topic, a two-week plan and every answer worked through, and keeps them.
What does it cover?
Programming, recursion, data representation, Boolean logic and algorithms.
What grade do most students get?
In 2026, 5.7% of OCR A-level Computer Science students got A* and 23.2% got A or above.
