Teach it. Set it. Revise it.
Most platforms stop at quizzes. One membership gives you the lessons to teach from, homework that marks itself, and revision students come back to, so your time goes on teaching.
Teach it
Every lesson is laid out to teach from the front of the class, and you can download each one as a PowerPoint show. No rebuilding, no prep.
No lesson prep
Set it
Set lessons and quizzes with a due date in a couple of clicks. Every quiz marks itself, so you can see who has done the work without lifting a pen.
No marking
Revise it
XP, levels, achievements and class leaderboards turn revision into something students compete over, right up to the exam.
Less chasing

The Tracker
Every student’s progress on one screen
Quiz marks for every lesson, colour-coded so the gaps stand out, alongside each student’s study time and attempts.
- Switch between best, worst, first and most recent marks
- Open any student to see their weak spots and missed tasks
- Export to Excel for reports and parents’ evenings
Insights
Know what to re-teach before your next lesson
Class Insights picks out the quizzes your class found hardest and the students who need a nudge. Lesson Insights then shows how the class answered each question, hardest first.
- The quizzes worth re-teaching, weakest first
- The students who need your attention, and why
- Effort against attainment, to spot who is working hard but stuck

Made by a teacher, trusted by teachers
Started by Daniel Richardson for his own students, still written by a teacher and textbook author, and rated a Top Teaching Efficiency Tool in the EdTech Impact Awards 2025.

We bought a subscription after poor January exam results and the students who revised using the site went up a whole grade in the resits.
Aaron Cocker, Teacher, Oldham College
It helps me catch students up who start late, reinforce learning and understanding in the classroom and it saves me a lot of time due to the self marking quizzes.
Barry Williams, Teacher of Computer Science, Omega Multi Academy
Outstanding resource, which maps directly to the specification. The low stakes multiple choice questions are worded well and are very effective.
Nichole Davis, Subject Leader of Computing, The John Fisher School
