The ClassCubes method
Walk into the exam hall knowing exactly what you know.
Ten minutes a day on your phone. The whole syllabus, filled topic by topic and kept until the exam, with proof your parent can read in a minute.
No sign-up for the test. The daily workout is free, every day.
Remember more
Every minute is recall, the one kind of study that makes knowledge stick. What you learn here is still there in the exam hall.
Train until competent
A topic is not finished until you have got it right on separate days. The app keeps a few topics in play and finishes them before starting more.
Know where you stand
Every topic is a cube that fills, fades and shows when it is secure. One glance at the wall tells you what to do today.
Why revision fails most students
Most revision feels productive and is not.
- Reading feels like learning. Re-reading and highlighting build familiarity, not the ability to produce the answer under exam pressure.
- Cramming fades by next month. A topic learned in one long evening is mostly gone a few weeks later, and the exam is months away.
- Nobody knows where they stand. The gaps show up when the paper comes back, too late to fix.
- Mistakes stay hidden. A wrong idea that is never tested stays wrong until the exam tests it.
Six rules we built the app around
Each rests on findings in the science of memory that have held for decades. Our work is combining them into a ten-minute habit a teenager keeps.
- 01
Answer, never just read.
A workout is questions, start to finish. Pulling an answer from memory is what makes it stick. Explanations are short and come straight after.
- 02
Learn a topic over days, not one night.
The app will not let a topic be finished in one evening. Knowledge recalled on separate days, with sleep between, is the knowledge that survives to the exam.
- 03
Come back before you forget.
Finished topics return for a quick check around the time they would start to slip, and again later. Each successful return pushes the next one further away.
- 04
Mistakes cost nothing and teach the most.
A wrong answer gets a short explanation at once. Nothing is taken away. The topic returns with a different question and only moves on once you get it right.
- 05
Finish topics, one at a time.
A few topics in play, finished before new ones start. Mastered means right on separate days, not one good evening. Every subject moves forward in turn.
- 06
Mix it, the way the paper does.
Every workout draws on several topics and subjects, so you practise spotting which kind of problem this is and which method it needs.
For parents
Proof, not promises.
You see the days trained, the topics mastered and what changed this week, in plain figures, without installing anything. Multiple choice is part of the paper, not all of it, and ClassCubes says so. A predicted grade with the evidence behind it, and a weekly report, are coming.
- Days trained
- Topics mastered
- What changed this week
For tutors and teachers
Your class, cube by cube.
Make a class, share one link in your class's WhatsApp group, and see which topic to teach again. Your students keep their free daily practice; you see them by nickname and real name and nothing else. Every plan starts with a free trial; the plans are on the teachers page.
Honest limits
- Multiple choice is part of the paper, not all of it. Written answers need practice with a teacher.
- It is a habit, not a miracle. Ten minutes a day over months is what moves a grade.
- Questions are written fresh to the official syllabus and textbooks, and checked before release. Find one that is wrong and you can flag it from the question itself.
Find out where you stand in three minutes.
The daily workout is free, every day, for ever. The app is in English for now; questions come in English, Sinhala and Tamil medium.
