The revision challenge every Computer Science teacher knows

You want your students revising more, but there is only so much time in your week to set tasks, mark responses, and chase up who has actually done the work.

Marking takes up too much of your time

Your students need regular revision practice to prepare for both J277 exam papers. But marking practice answers across multiple classes takes hours you don’t have. Time you could be spending on planning, teaching, or giving targeted support.

Two papers’ worth of content to retain

Between Computer Systems and Computational Thinking, J277 covers a huge amount, from CPU architecture and networks to algorithms and programming. Students need to hold all of it, and they won’t manage that from lessons alone. Without regular, structured practice between now and the exams, most of it fades long before they sit them.

Getting students to actually revise

You want students practicing outside of lessons, but without something structured, most won’t bother. KnowItAll Ninja gamifies revision so students compete on a class leaderboard, track their own progress, and actually want to come back and practice independently.

We bought a subscription after poor January exam results and the students who decided to bother with revision using the site went up a whole grade in the resits. Some from M to D and for others it made the difference between an N and a P.

Built around the OCR GCSE Computer Science (J277) specification

KnowItAll Ninja covers both externally assessed papers of the OCR GCSE Computer Science qualification. Questions are written to match the specification, so students practise exactly what they need for the exams.

Exam preparation in one place

Both J277 papers are assessed by written exam, so the whole qualification is exam revision. KnowItAll Ninja gives students one consistent place to revise across both papers, rather than scattering practice across worksheets and handouts.

Unit coverage

GCSE Computer Science is assessed entirely by two written papers, both sat by every student. Our quizzes cover the content of both, giving students one consistent place to revise for their exams.

How teachers use KnowItAll Ninja

Designed to work alongside your teaching, not replace it.

Set it as homework to address the forgetting curve

Assign lessons with deadlines directly from the platform. Students complete lessons and quizzes at home, reinforcing what was taught in class, and you can see who actually did it.

“Always set units as homework to reinforce teaching in class. Thank you, makes tracking much easier!”

Jen E., Teacher

Answers are checked automatically, saving time

Every quiz is auto-marked. No more manually checking short answer questions or chasing students for responses. Results go straight to your analytics dashboard.

“Dan has saved me so much work it’s unreal.”

Neil C., Teacher

Track progress and spot areas to revisit

Per-student and per-topic analytics show exactly where understanding is breaking down. Identify who needs more support before it shows up in their grade.

“We purchased your subscription this year and it is working very well, students are happy and I love the tracking it offers.”

Kasia K., Teacher

Motivation taken care of

The gamification layer (XP, levels, leaderboards, achievements) makes students compete to revise. Many teachers report students using it beyond what’s assigned.

“Students loved competing against each other.”

Hazel L., Teacher

Created by a Computing teacher

KnowItAll Ninja was originally built by Daniel, a computing teacher, to help his own students revise more effectively for computing and IT qualifications.

The quizzes and questions are written specifically for courses like OCR GCSE Computer Science, and are now used by thousands of students and teachers across the UK.
